Question

Evaluate cos^2 θ for cos θ = sqrt(3)/2

Answer 1

\[\Large\rm \cos \theta=\frac{\sqrt3}{2}\]Soooooo, they want you to square it....? Is that all?\[\Large\rm \cos^2\theta=\left(\frac{\sqrt{3}}{2}\right)^2\]\[\Large\rm \cos^2\theta=\frac{3}{4}\]Or do we need to do something more with this? 0_o
Confusing directions...

Answer 2

Oh that was it thank you! I just didn't understand how to do it

Answer 3
