We want to find out the time during which the stone is above a certain point. As this stone is thrown upwards we know that the first time it passes this point it will be on its way up and when it passes t...

To begin with, this question requires you to differentiate the curve y = 4x² + 7x +1 in order to find the gradient. To differentiate this function y in respect to x, we need to reduce the power...

dy/dx = 34

First equate the factor to equal 0 then solve:x -2= 0;x = 2;
now plug the number 2 into all the X values:
(2)^2-4(2) + 4 = 8-8 = 0

The first stage of this question involves differentiating the equation of y in terms of x given to us. In order to differentiate, we first need to write y in terms of base x (where all the terms are x to ...
