Trigonometry Identities - Pythagorean (Tan^2 and Sec^2) to Identity (Degrees)

This math topic explores trigonometric identities involving the functions tangent (tan) and secant (sec), specifically focusing on identities that connect \( \tan^2 \theta \) and \( \sec^2 \theta \) in degree measure. The problems require converting expressions with \( \tan^2 \theta \) and \( \sec^2 \theta \) to other trigonometric forms using Pythagorean identities. Questions present a trigonometric expression with tan squared or sec squared and ask for completion of the related Pythagorean identity, choosing between potential answers which involve different trigonometric functions.
