WebJun 1, 2024 · Use the double-angle formula for cosine to write cos(6x) in terms of cos(3x) . Solution cos(6x) = cos(3x + 3x) = cos3xcos3x − sin3xsin3x = cos23x − sin23x Analysis This example illustrates that we can use the double-angle formula without having exact values. WebA right triangle with sides relative to an angle at the point. Inverse trigonometric functions are useful when trying to determine the remaining two angles of a right triangle when the lengths of the sides of the triangle …

WebMathematically, it is written as cos -1 (x) and is the inverse function of the trigonometric function cosine, cos (x). An important thing to note is that inverse cosine is not the reciprocal of cos x. There are 6 inverse trigonometric functions as sin -1 x, cos -1 x, tan -1 x, csc -1 x, sec -1 x, cot -1 x.
