(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

4sec180° - 2sin^{2}270°

3. The attempt at a solution

sec(180 is -1.

So we have 4(-1) which is -4

sin^{2}(270 is -1

So we have 2(-1)

This now reads -4 - -2

Answer = -2

Is this correct or do I suck at this? =(
