is cos inverse equal to sec

is cos inverse equal to sec Since none of the six trigonometric functions are one to one they must be restricted in order to have inverse functions Therefore the result ranges of the inverse functions are proper i e strict subsets of the domains of the original functions For example using function in the sense of multivalued functions just as the square root

arccos x is a value whose cosine is x whereas sec x frac 1 cos x The two kinds of inverse trigonometric functions can feel a bit esoteric when you re new to The inverse of cos is not sec The secant is the inverse of the cosine function a trigonometric function The Arcos function is the opposite of the cos function

No they are not equal Here is why We can look at an algebraic approach to arcsec and arccos first Arccos x y Cos y x 1 sec y x The range of the inverse cosine function is 0 leq y leq pi so it delivers angles in the first and second quadrants Compare to the inverse sine whose outputs are angles in the first or fourth quadrants

Secant can be derived as the reciprocal of cosine The inverse secant function arcsec For every trigonometry function such as sec there is an inverse function that works in reverse These inverse functions have the same name but with There are 6 inverse trigonometric functions as sin 1 x cos 1 x tan 1 x csc 1 x sec 1 x cot 1 x Inverse cosine is used to determine the measure of angle using the value of the trigonometric ratio cos x In this article we will understand the
