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...
This video shows the method to change a word problem into algebra and to identify rational numbers among a group of numbers. In the first part of the video we take a word problem namely - The product of 9 and seven, less than a number. 9 multiplied by something can be expressed as 9(). The unknown number can be expressed as 'x'. Seven less than a number can be expressed as x - 7, so that the final equation becomes 9(x - 7). In the second part we are given a list of numbers. A rational number ...
This video describes how to divide fraction values using simple method. Example we will take as in video "12" should be divided with "1/2" that is "12%(1/2)=?". This is the example we should solve. In first step we has to flip the "Denominator" to easily find the output. So now, we can rewrite the example as "(12/1)%(1/2)".It is in the form of division, when we convert it to multiplication it will change as "(12/1)/(1/2)" and then "(12/1)*(2/1). So, denominator "1/2" flipped to "2/1". In the ...
Not sure how to balance a chemical equation? According to the rules of chemistry, matter must be conserved in chemical reactions. When you balance a chemical equation, you account for all of the matter in the reaction.
You can't add fractions when the denominators are not the same - it's a rule in math you can't ignore!
You should always try to reduce a fraction until it can't be reduced anymore. To do this, look at your fraction and figure out the greatest number BOTH the numerator and denominator can be divided by. This is called the GCF - the greatest common factor. In the video, the problem you must solve is (15/18). What number can be divided into both 15 and 18 evenly? The answer is 3.
