Differentiation is a method used to find the rate of change of a function with respect to a given variable, eg. how f(x) changes with respect to x. There are different ways to find the derivative of a fun...

Ask if they have found derivations before.If not:When we differentiate a polynomial like this by using the fact that:The derivative of A^x is xA^(x-1).So, we multiply the unknown variable, A, by the power...

Every straight line can be written in the form y=mx+c.(If they seem completely unfamiliar with concept):M is known as the gradient of the line, which says how steep the line is. The bigge...

By the sine rule, sin^-1(5/13)=22.6 degrees.Equally, by the cos^-1(12/13)=tan¹(5/12)=22.6 degrees.

First of all, replace sinxcosx with 1/2 sin2x. Then you should let U=1/2 Sin2x and replace that in the formula. If y=arctan(U), then U=tany. work out dU/dy which is Sec²y. Using the trigonometr...
