Often, it can seem daunting when you are asked to differentiate a function that looks particularly messy. However, it's really quite simple if you break it down in easy to manage steps....
How to integrate ln(x)?
In order to integrate log x of base e, we are going to apply integration by parts.
Recall that the formula for integration by parts i...
Reminder - a cartesian equation is written in terms of x and y (e.g. y = 2x + 3) while parametric equations are written with x and y separately in terms of t.
Example: Find the cartesian ...
Finding stationary points.
You can find stationary points on a curve by differentiating the equation of the curve and finding the points at which the gradient func...
Using integration by parts: split xcos(x) into x multiplied by cos(x). Differentiating x gives 1 and integrating cos(x) gives sin(x). The integral of xcos(x) can therefore be rewritten as xsin(x) - integr...
