Pythagorus' Theorem: A² + B² = C²

Therefore... 1.5² + B² = 6.8²  

= 2.25 + B² = 46.24

B² = 46.2...

x^3/3  +  1/x

Take a look at the expression below:

x² + 4x + 3

To complete the square you have to focus on the number before the x or the (x coefficient).

In this case, this number is 4....

Binomial:

1. A single trial has only 2 possible outcomes: success or failure

2. A fixed number of trials, n

3. Trials are independent

In order to integrate (cosx)^3, there is no given rule (by-parts, 'try' method, chain rule) which we can follow. We would need to split it into (cosx)^2 and cosx. Then use the identity: (sinx)^2 + (cosx)^...
