To integrate this function integration by parts is used where u = lnx and v = 1. The process of integration by parts is then carried out with the final answer being xlnx -x +c. 

The formula for int...

An easy way to integrade and differentiate simple equations is by bringing up all the denominators, in this case rewrite 3/x^2 into 3x^-2. Thus it will be easier to manipulate the powers. For Integration ...

i) Using the power rule, f'(x) = 3x² - 6x ii) To find stationary points, set f'(x) to 0: 3x² - 6x = 0. 3x(x - 2) = 0. x = 0  or  x = 2 So the co-ordinates are (0,f(0)) = (0, 1), and ...

1/(x²) can be written as x^-2

We know that to differentiate you need to multiply by the value of the old power and minus 1 from it. This means dy/dx of y=...
