- Don't forget to add a +/- sign to the square root
- Because of this +/- sign, you are likely to get 1 answer from every quadrant.
- Base angle is always positive
- If uncertain, always remember to sub the value of x back to the original equation to see if it fits. You can also find and test other values of x (eg. alpha, 180-alpha, 180+alpha, 360-alpha)
