WebConventionally, an abbreviation of each trigonometric function's name is used as its symbol in formulas. Today, the most common versions of these abbreviations are "sin" for sine, "cos" for cosine, "tan" or "tg" for tangent, "sec" for secant, "csc" or "cosec" for cosecant, and "cot" or "ctg" for cotangent. 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. florian hascher https://ctemple.org

WebFree math problem solver answers your trigonometry homework questions with step-by-step explanations. WebThe value of cos 135 degrees can be calculated by constructing an angle of 135° with the x-axis, and then finding the coordinates of the corresponding point (-0.7071, 0.7071) on the unit circle. The value of cos 135° is equal to the x-coordinate (-0.7071). ∴ cos 135° = -0.7071.
