what is sec cos

what is sec cos The cosecant csc The cosecant is the reciprocal of the sine It is the ratio of the hypotenuse to the side opposite a given angle in a right triangle A C B a c sin A opposite hypotenuse a c csc A hypotenuse opposite c a The secant sec The secant is the reciprocal of the cosine

In this right triangle denoting the measure of angle BAC as A sin A a c cos A b c tan A a b Plot of the six trigonometric functions the unit circle and a line for the angle 0 7 radians The points labelled 1 Sec Csc represent the length of the line segment from the origin to that point As far as I know arccos x is the inverse cosine function cos x 1 and sec x 1 cos x source Wolfram Alpha So why aren t they equal Thanks in advance functions trigonometry inverse Share Cite edited Apr 18 2022 at 15 52 Jos Carlos Santos 428k 293 276 466 asked May 15 2013 at 23 35 Lince Assassino 273 1 2 6 6
