How To: Find the midpoint of two points using formula

Find the midpoint of two points using a easy formula. Each coordinate has a x and y. X being the first number and y being the second number. So using the formula of x one plus x two then divide the sum by two. Using the same formula with the y coordinates. After plugging the numbers in the formula add the two x coordinates and divide by two. If you follow the same steps for the y coordinate take the two numbers and you have the midpoint of your two coordinates.

How To: Find the horizontal asymptotes of rational functions

Finding horizontal asymptotes is very easy! Not all rational functions have horizontal asymptotes. the function must satisfy one of two conditions dependent upon the degree (highest exponent) of the numerator and denominator. If the degree of the numerator is equal to the degree of the denominator, then the horizontal asymptote is y= the ratio of the leading coefficients. If the degree of the denominator is greater than the degree of the numerator then y= 0. If the degree of the denominator i...

How To: Use vinegar & hydrogen peroxide to reveal fingerprints

Learn how to find latent finger prints on brass surfaces, such as fired cartridge cases. Called the Acidified Peroxide method, using only white distilled vinegar and hydrogen peroxide that you can find at your local drugstore, you can uncover fingerprints that is usually impossible to see using other methods.

How To: Find the standard error of the mean

In this video the tutor explains about the standard error of the mean. He starts explaining by drawing the diagram of a distribution and now he takes ten samples from the distribution and starts plotting them. He says that in theory if we do it infinite times then we can obtain the sampling distribution of the sampling mean. For the example he takes the number of samples as 10. Now depending on these values of n we can get different sampling distributions. Now he intends to find the mean of t...

How To: Find a central angle

How To: Use INDIRECT, TEXT, and SUBSTITUTE in Excel

ExcelIsFun will show you how to use indirect text and substitute in Excel. Select any date and product and create an intersession. Use Vlookup to look up your columns. Use the match function to find the value range. To do the same thing with dates, highlight the dates and names. You then let the name look for indirect. Your space operator tells you two ranges to find the intercept. Take the text and substitute for the dashes. Use the text function on the value and format it.

How To: Use the TOA formula in trigonometry

The video is a tutorial in trigonometry. The teacher teaches that the tangent or the tan of an angle is the ratio of the opposite side to the adjacent side of a right angled triangle. If one side and one angle is given then the value of the unknown side can be found by solving the equation tan of angle is equal to opposite upon adjacent side. If the angle is to be found then the tan inverse of the value is seen in the calculator.

How To: Ask a girl out for Valentine's Day

This video will help you feel more comfortable approaching someone new to spend Valentine's Day together. It can all start with a simple and innocent question.

This could be just the encouragement you need to take the first step in starting a new relationship or just getting to know someone whom you have found interesting. The best part to...

How To: Solve for the missing ratios or proportions

In this video the tutor shows how to solve the missing ratios or proportions. He explains it with an example, where a number in one of the ratios is missing and he intends to find this value. He shows the example of cross multiplication, where you multiply the values on the either side of the equation diagonally and finally solves the equation which results in the value of the unknown value. This is an introductory video explaining how to use rations and proportions to find missing values.

How To: Find the coordinate of a point

In this video the author shows how to plot a point on the coordinate plane. He explains about the coordinate plane and shows how to read and write points to it with an example. He says that any point on the coordinate plane has an x, y- coordinate values. He says that for any point its projection on the x-axis is its x-coordinate and the points projection on y-axis is its y-coordinate. He shows how to find this out for a sample value and plots the coordinates of it. In this video the author u...

How To: Find the surface area of a sphere

In this tutorial the instructor shows how to find the surface area of a sphere. He explains the equation to calculate the surface area of a sphere as 4 * Pi * r * r , where r its the radius of the sphere. Now if you have the radius of the sphere, by substituting its value in this equation and substituting the value of Pi, you can obtain the surface area of a sphere. If you want to compute the surface area of a sphere watch this video where it is clearly explained how to compute it along with ...

How To: Translate a shape

Learn how to translate shapes with a few simple steps. - First step: Find the new verticals under the transformation which are T3,2. Values are A=(-5,-8), B=(-3,-4), C=(-8,-3), D=(-6,1). Find the points of the verticals on the graph and connect the points one by one until you can get one shape.

How To: Find a slope of a line parallel/perpendicular to it

This video tells you how to find a slope of a parallel / perpendicular to it. In the equation y = mx + c, m is the slope. To calculate the slope of a line that is parallel to another line, you have to consider the rule m1 = m2 which means slope of the first line m1 is equal to the second line m2, if both the lines are parallel. Take the equation y = 2/3x - 7.2/3 is the slope. According to the rule m1 = 2/3 and so m2 = 2/3.Now to calculate the slope of perpendicular line you have another rule ...

How To: Make dark skin glow

The key to this technique is to find the right bronzer for the skin that you are applying the makeup to. Most bronzer's disappear on dark skin. So you want to find a cream based bronzer with a lot of pigments. You want a bronzer that is intense enough that you are able to see a subtle spot of color on the skin when you rub it on. To make your skin naturally warmer mix your foundation and your bronzer together. Start by mixing up a mixture that is three parts foundation and one part bronzer. A...

How To: Find points of intersection in different equations

In this tutorial the instructor shows how to solve linear and quadratic equations.

Now he uses comparison to compare the values of y in both the equation resulting in a equation in x. Now he shows the factors of the obtained polynomial equation and there by finding the values of x coordinates. Now he substitutes these values of x in the origin...

How To: Add fractions with like and unlike denominators

This video shows a tutorial of adding fractions. The first example shows a fraction that has like denominators so all you had to do is add the denominators. In the second example it shows two fractions that do not have like denominators. Therefore, you need to find the greatest common factor among the two denominators. Once this is found, you multiply the fraction on both the numerator and denominator to make both of the fractions match. Then all that is left is to add the numerators to finis...
