WebIn Trigonometry, different types of problems can be solved using trigonometry formulas. These problems may include trigonometric ratios (sin, cos, tan, sec, cosec and cot), Pythagorean identities, product identities, etc. Some formulas including the sign of ratios in different quadrants, involving co-function identities (shifting angles), sum & difference … 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
