How To: Simplify exponential expressions in basic algebra

The video shows how to solved mixed property problems using the exponent rules. See if there are any rules you can apply to the problem until you get to a point where you can't simplify anymore. The instructor shows in the example problem that the two bases are the same, but there is extras happening the numerator. The power to power multiply rule is applied removing the extra issues from the numerator. Next the quotient rules is applied as there is the exact same base to the power so we keep...

How To: Light for video to get a filmic look

In this video, Tony Reale describes some cinematography tips for video lighting. He focuses mainly on different ways to capture the look of video. The lighting style he's using in this video is a 2-light setup. One light is reflecting off a foam core and is placed at the right side of the room. The second light is acting as background light and is smaller and placed in the back, right corner of the room.

How To: Make a mini polymer clay waffle for a dollhouse

Garden of Imagination demonstrates how to make miniature blueberry polymer clay waffles for use in a doll house. Starting with a small ball of either ecru-colored clay, or pearl-white, you can blend in tiny black glass pebbles to resemble blueberries or raisins. The ball is then pressed onto a small strip of dry-wall tape that has an open weave to it, to make waffled impressions. The strip with the clay on it is run through a pasta-maker at a setting of “four” to flatten the clay into the mes...

How To: Solve a linear system by graphing in math

This video teaches you how to solve a linear system by mathematically graphing it out. The video starts off with a problem, asking to solve the system, with two given equations. To solve the system, one would insert 0 for x and solve for y in the first equation to obtain a point. Then one would insert 0 for y and solve for x at the second point. Afterwards, insert 1 for x and solve for y to obtain the third point. For the second equation, do the same thing, inserting 0 for x, 0 for y and 1 fo...

How To: Graph linear inequalities

In this video the instructor shows how to graph linear inequalities. A linear in a equation is almost similar to a linear equation except for the sign in the equation. Now treat the in equation as a linear equation and graph the line. So substitute the lesser than or greater than symbol in the liner in equation with the equals to sign and graph the equation. Find the slope of the equation and identify the points that the line passes through. Now take a point on the either side of the pointed ...

How To: Find the opposite and absolute value of a number

View the absolute value of a number as its distance from zero. When you take the absolute value of a number, you always end up with a positive number (or zero). Whether the input was positive or negative (or zero), the output is always positive (or zero). For instance, | 3 | = 3, and | _3 | = 3 also. This property that both the positive and the negative become positive makes solving absolute-value equations a little tricky. But once you learn the "trick", they're not so bad. Let's start with ...

How To: Understand diffusion & osmosis

Inside the container we have some water molecules and inside those water molecules we have some sugar molecules. We have more water molecules so in this case the thing which is more of called SOLVENT and the thing which is lesser is called SOLUTE. We can say sugar molecule dissolves in the water. The combination of Solvent and Solute is called the SOLUTION. Diffusion is spreading the molecules from high concentration to low concentration. If we take two containers of water which are joined fr...

How To: Perform the Barus effect

Watch this instructional science video to observe the Barus effect in action. A dyed solution of POLYOX (polyethylene oxide - it is the stuff used as the lubricant on the strip found in all modern razors) is extruded from a 50 mL syringe. On exit, a marked swelling in the liquid stream several times the diameter of the orifice is observed. The effect is referred to as the Barus Effect, but it also goes by several other names including the Merrington Effect, Die Swell, and Extrudate Swell.

How To: Create a textured face in 3ds Max 8

This is a three-part 3ds max video tutorial that takes a look at using reference photos for creating a head texture.

How To: Calculate the circumference of a circle

This video shows how to calculate the circumference of a given circle. The video first describes the circumference or perimeter of a circle as the distance around the outside of a circle. To find the circumference we need either the radius or the diameter of the circle. When you know the diameter of the circle, the formula to find the circumference denoted by 'C' is 'pi' times the diameter, where 'd' is the diameter and 'pi' is a constant, the approximate value being 3.14. And when you are gi...

How To: Use implicit differentiation

Taking this formula 9x²+y²=9 your instructor shows you how to find the solution for the variable y. Finding a second derivative is no more difficult that finding the first derivative, you only have to do the problem equation through twice. The derivative of 9x² will be 18, of y² will be 2y [this is the same as 2(y), 2 x y or 2 * y]. The problem now goes -18x + 2y dy/dx=0. This equation is solved for dy/dx making the next step in the problem go -18x 18x+2y dy/dx=0-18x, 2y dy/dx= -18x. The next...
