There are a few ways to tackle this particular style of problem. First off we can try doing it without using any bracket theory and just focus on the raw numbers (a somewhat simpler approach). Step 1: We'...

(3x + 1)² = 9x² + 6x + 1 (3x - 1)² = 9x² - 6x + 1 (9x² + 6x + 1) - (9x² - 6x + 1) = 12x 12x/4 = 3x Therefore for all positive integers of ...

 u = Cos(x³)

To differentiate this function we will use the chain rule. Firstly we will set x³  to another variable name such as v. So now v = x³ . Lets differentia...
