WebArccosine is the inverse of the cosine function and thus it is one of the inverse trigonometric functions. Arccosine is pronounced as "arc cosine". Arccosine of x can also be written as "acosx" (or) "cos-1 x" or "arccos". If f and f-1 are inverse functions of each other, then f(x) = y ⇒ x = f-1 (y). So y = cos x ⇒ x = cos-1 (y).This is the meaning of arccosine. how much is keapWebDec 14, 2024 · Trigonometric ratios are defined as the sides and angles of a right-angled triangle are deal with in Trigonometry.
