This is a relatively difficult equation to differentiate as there are various parts to consider.Firstly, we will let u=2^x and v=(5x^2+5x)^2 in the product rule. Then the differential of u is (2^x)ln(2). ...

To solve this equation we must first factorise it. To do this we initially write two brackets containing x equal to zero like this (x )(x )=0.Then we want to identify the other part of our bracket. Th...

Percentage profit = (profit/original )x 100

To find the profit; £38x5+11 - (6x£25) = £51

Percentage profit = (£51/6x25)x100 = 34%

First determine the y coordinate of the curve at the given x coordinate, in this case, y = sin²(pi/2)/(pi/2) = 1²/(pi/2) = 2/piDifferentiate the function with respect to x to determi...

The best way to think about this question is to imagine the plan of the cube. Looking at this you would see that there are 6 identical squares. Therefore you should realise that to work this question out ...
