# Checking Differential equation using GC

GC can be used to check the solution to differential equation.

**Example from 2014 P1 Q10**

Suppose we want to check whether the following solution to 10 iv is correct:

Enter the following in GC

Since Y2 and Y3 gave the same values, the solution is correct.

# Using GC to calculate Expectation and Variance of Discrete Random Variable

**Solution**

Enter the data in the GC as follows:

Variance can also calculated using the GC as follows:

# Shortcut method for solving 2016 challenging complex number

**2016 P1 Q7**

**Solution**

a) Hence part

Common methods to find the other root are long division or compare coef. A faster method is to use the sum of roots taught in additional maths.

b)
