To differentiate x 2 you bring the power of x down, then reduce the power of x by 1, so d/dx(x 2 ) = 2x 1 ln3x differentiates to (d/dx(3x))/3x = 3/3x = 1/x e^x differentiates to (d/dx(x)) e^x = 1 e^x Therefo...

To differentiate you must look at each term separately. So for x^2 to differentiate we bring the two down to multiply in front of the x and then take one away from the power leaving 2x. For 4x, x is to the p...

Since the diameter is 130cm, the radius is half of this, so it is 65cm Area is Pi radius 2 . This means the area is Pi (65cm) 2 This means the area is Pi*4225cm 2

The chain rule works so that if you have y=f(x)g(x), where f(x) and g(x) are functions of x, dy/dx = f'(x)g(x) + f(x)g'(x)

Take for example, the equation 13a + 6a 2 = −6 rearrange the questions into the form ax 2 +bx+c=0 6a 2 + 13a + 6 = 0 method 1: cross-multiplication method you use the cross multiplication method to find the ...
