This topic focuses on solving trigonometric problems specifically related to Pythagorean identities. Students practice finding the cosine of an angle given the sine, using the identity \( \sin^2(\theta) + \cos^2(\theta) = 1 \). Each problem also involve considering the angle’s quadrant to determine the correct sign for cosine. This is an introductory level exercise, designed to help students familiarize themselves and reinforce their understanding of foundational trigonometric identities and concepts.
