What is cos−1(.60) ? cos−1(0.6)= 53.1° Explanation: Note that cos−1 ... Cosines Tangents Cotangents Pythagorean theorem Calculus Trigonometric substitution Integrals ( inverse functions) Derivatives v t e In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. As you can see below, the cos -1 (1) is 270° or, in radian measure, 3Π/2 . '-1' represents the minimum value of the cosine function ever gets and happens at Π and then again at 3Π ,at 5Π etc.. (See graph at bottom ) Below is a picture of the graph of cos (x) with over the domain of 0 ≤x ≤4Π with cos -1 (-1) indicted by the black dot..
