sin^2x = (sinx)^2 Squared Trig Function Notation

We went into verifying some equations with trigonometric. They involved angles in both degrees and radians.

Sometimes with equations that had notation of something like sin^2x, which means (sinx)^2 but is the more common notation.

No calculators used in the problems, so the angles all were variations of 45-45-90 or 30-60-90.
