Web15 Dec 2024 · Then sec (θ) = 3x. It follows from the definition of secant, and subsequently the Pythagorean identity, that • cos (θ) = 1/sec (θ) = 1/ (3x) • sin (θ) = √ ( (3x)² - 1²) = √ (9x² - 1)/ (3x) but remember that we assume 0 ≤ θ ≤ π. Over this interval, sin (θ) can be either positive or negative, which we account for by replacing x with x , so that Web9 May 2024 · Answer: Step-by-step explanation: sustiute 1 and -1 to x y=tan^3(x) you get postive and negative values , odd function. y=1/sec^3 x is even and same goes on
