Multiplication and addition of complex numbers. Four parts.

Elementary examples of multiplication and addition of complex numbers. Four parts.

Trigonometric equations with degrees

Simple trig equations with radians

Convert degrees to radians and radians to degrees.

Definite integation of basic functions.

Differentiate $\displaystyle (ax^m+b)^{n}$.

This question tests the student's ability to solve simple linear equations by elimination. Part a) involves only having to manipulate one equation in order to solve, and part b) involves having to manipulate both equations in order to solve. 

Some quadratics are to be solved by factorising
