Web8 rows · The formula for cos^3x is given by cos^3x = (1/4) cos3x + (3/4) cosx. We can derive this ... Mathematically, the cosine function formula in terms of sides of a right-angled … WebPrecalculus. Solve for x cos (3x)=1. cos (3x) = 1 cos ( 3 x) = 1. Take the inverse cosine of both sides of the equation to extract x x from inside the cosine. 3x = arccos(1) 3 x = arccos ( 1) Simplify the right side. Tap for more steps... 3x = 0 3 x = 0. Divide each term in 3x = 0 3 x = 0 by 3 3 and simplify.
