To make this equation easier to differentiate it would be easier to write it using index rules as y = 4x^3 - 5x^-2 From here we can begin to differentiate: dy/dx = 3*4x^(3-1) - (-2)*5x^(-2-1) Then finally...

Firstly, let's split the equation "xcosx" into two parts to integrate them separately. 1) Let u=x and dv/dx=cosx 2)As the integral of x is 1, du/dx=1 3)To find v, we integrate cosx to get v=sinx...

This is an interesting way to get students thinking about what narrative techniques a writer can use to keep the reader interested. This might be a nice question to explore a students understanding of nar...

This question is a great way of both examining the student's understanding of 'anxiety', how to describe and then bring an investigatory eye to the text to find word, and phrases that relate to this. It's...

In maths when we are asked to re express something we really only have 2 tricks. Multiply by 1, or add Zero. The hard part is finding how to express 1 or zero to suit the problem. For this one we should m...
