WebbTrigonometric Identities. ( Math Trig Identities) sin (theta) = a / c. csc (theta) = 1 / sin (theta) = c / a. cos (theta) = b / c. sec (theta) = 1 / cos (theta) = c / b. tan (theta) = sin (theta) / cos (theta) = a / b. cot (theta) = 1/ tan (theta) = b / a. sin (-x) = -sin (x) Webbtan^2 = sin^2+cos^2 = 1 << this we can agree on the solutions tell us to divide both sides by cos^2. so sin^2/cos^2 + cos^2/cos^2 = 1/cos^2 and 1/cos^2 is sec^2 << still following then somehow it says therefore tan^2-1 = sec^2 so it replaces the entire first argument with sec^2, completely ignoring that 1 we were supposed to deduct from tan.
