Showing all your working, evaluate ∫ (21x^6 - e^2x- (1/x) +6)dx

When integrating a long chain of functions, we can integrate each term seperately and combine them. Let us now integrate:∫21x6dx = 21∫x6dx. Using the Power Rule [∫xadx = (...

Differentiate y=x(e^x)

Write as y=uv u=x v=ex

du/dx=1 dv/dx=ex 

Using the product rule, dy/dx=vdu/dx + udv/dx

So dy/dx=ex(1)+x(ex...

Solve the equation 3^(5x-2)=4^(6-x), and show that the solution can be written in the form log10(a)/log10(b).

So we have the equation initially in the form 3^(5x-2)=4^(6-x), and as the solution involves log10, then  a sensible first move would be to take log10 of both sides, giving log10(3^(5x-2)) = log10(4^(6...

Prove that (sinx + cosx)^2 = 1 + 2sinxcosx

Starting on the left hand side we can expand out the brackets to get:
(sinx + cosx)(sinx + cosx)
sin2x+sinxcosx+sinxcosx+cos2x
Grouping together the like terms we can ...
