Differentiation is pretty simple! It has a set of instructions you need to follow and then you should be good to go!

For example, differentiate x^6
The first step is to bring down t...

1. Differentiate the Equation of the curve to find the gradient: y'=3x^2

2. The gradient of the tangent is found by substituting x=1 into y'=3x^2: Gradient of tangent=3

3. N...

We are given the substitution to use, so the first step is to differentiate "u" with respect to x. 

du/dx = -sin(x)

Now, to replace the "dx&q...

As we are differentiating a product (two things times together) we can use the product rule which is if:

                       y = u(x)v(x)

then

             ...

This question require us to rearrange the equation and solve it to find the vale of x.

Firstly we need to make sure all of the x are on one side of the equation. To put all the values of ...
