Using the implicit form derivative rule: y'=-F x ' / F y ' : y'=-(2 x sin(x+y)+x 2 cos(x+y)-5 y e x ) / (x 2 cos(x+y)-5 e x )

You must apply the chain rule whenever you see a function contained within another function. For example, if you were to differentiate (sin x) 2 you would apply the chain rule as the sin function exists insi...

Step 1- Get all the numbers on one side of the inequality sign and all the letters on the other side. Remember when a number is moved to the other side of an inequality, the sign infront changes from either ...

Let's answer the question by solving an example: Take (8x 2 * 5x 4 * 2y 3 )/(20x 3 ). Firstly, let's take a look at the first bracket and rearrange it so we have both numbers and variables grouped together: ...

First of all, I would ask the student what they think the question means and whether they have encountered a question like this before, so that I know where to start from. If the student is more of a visual ...
