To find the trigonometric functions of an angle, enter the chosen angle in degrees or radians. Underneath the calculator, the six most popular trig functions will appear - three basic ones: sine, cosine, and tangent, and their reciprocals: cosecant, secant, and cotangent. Sine -1 refers to the inverse sine function or arcsine. This function takes a value between -1 and 1 as the input and returns an angle in radians as the output. For example, if sin (x) = -0.866, then sin -1 (-0.866) = -1.047 radians. This is approximately -60 degrees which means that the angle whose sine is -0.866 is -60 degrees or -1.047 radians.

Arccosine 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.What is sin of arccos (x) The sine of arccosine of x is equal to the square root of ( 1-x2 ): cos (arcsin x) = sin (arccos x) = √1 – x2. x has values from -1 to 1: x∈ [-1,1] See Also: Sin of arcsin x, arcsin of sin x. What is arccos of sin (x) From a religious viewpoint, swearing or cursing is generally considered sin. The main reason swearing is considered sin is because it reflects evil intent coming from one’s heart, rather than merely the content of the word that is spoken.
