This math topic explores Pythagorean identities within trigonometry, focusing on the relationship between tangent (tan) and secant (sec) functions. Problems involve converting tangent values into their corresponding secant values using trigonometric identities, particularly the identity \( \tan^2(\theta) = \sec^2(\theta) - 1 \). The exercises also consider different quadrants for the angle (given in radians) to see how it affects the sign and value of secant, enhancing understanding of trigonometric functions across different quadrants.
