WebDec 20, 2024 · The Pythagorean identities are based on the properties of a right triangle. cos2θ + sin2θ = 1. 1 + cot2θ = csc2θ. 1 + tan2θ = sec2θ. The even-odd identities relate the value of a trigonometric function at a given angle to the value of the function at the opposite angle. tan( − θ) = − tanθ.

WebOct 28, 2024 · To solve it, add 1 to both sides and divide by 3: tan² ( B /2) = 1/3 and then take square root of both sides: tan ( B /2) = ±√ 1/3 = ±√ 3 /3 It’s important to remember to use the plus-or-minus sign ± when taking the square root of both sides; otherwise you could overlook some solutions. Step 3. Solve for the angle. WebSep 28, 2016 · The equation can be rewritten as. 10 sin x cos 2 x = 2 5 ( cos x + sin x) ( cos 2 x − sin 2 x) Since cos x ≠ 0 (or the right-hand side would be undefined), we can divide by 2 5 cos 3 x and set t = tan x, getting. 5 t = ( 1 + t) ( 1 − t 2) that becomes. t 3 + t 2 + ( 5 − 1) t − 1 = 0.
