How do you find arccos
WebInverse cosine is also known as arccosine. It is the inverse of cos function. Also, sometimes abbreviated as ‘arccos’. It is used to measure the unknown angle when the length of two sides of the right triangle are known. The other inverse trig functions are also named in a similar way as per given in the below table.

WebThe arccos is used to obtain an angle from the cosine trigonometric ratio, which is the ratio between the side adjacent to the angle and the hypotenuse in a right triangle. The function spans from -1 to 1, and so do the results from our arccos calculator. The range of the angle values is usually between 0° and 180°. 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).
