Let say you want to find solutions for t(theta) of an equation. You come to this part;

sin^2 t = 1/2

To get rid of that power two, would we have to square root the 1/2 and also put plus or minus?

How about tan^2 t = 1/2? Would we have to square root the 1/2 and also put plus or minus?

Thank you so much.
