With sequences we should follow the general formula of An + B.

The n refers to the position in the sequence i.e. for the 3rd number in the sequence (whic...

There are 5 steps you can follow to make this sort of problem easier to handle:

1) Line up all of the values in a column with the decimal points under each other 

2) Ensure ...

Pythagos Theorem states that 

a^2 + b^2 = c^2

So using the figures we are given the equation would look like this:

7^2 + 11^2 = c^2

We square the...

You should begin by identifying all the Trigonometric Identities that may be useful in this problem. Specifically, cosecx=1/sinx tanx=sinx/cosx 1/cosx=secx and possibly tan^2x + 1= sec^2x. I began by c...
