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. dwr radioWebWhat is the value of cos 15°? Get the answer to this question and access a vast question bank that is tailored for students.
