how to solve y=arcsin(sin x)....arccos(cos x)....arctan(tan x)....if x DOESNT belong to its respective domains.....?

can u give me a algorithm for solving it quickly?

for arccos(cox x)?.....can you give me a better algorithm

hi FRG

you have to use trigonometric transfromation for sin ,cos , tan ,sec,cosec,cot

to change it in the priciple values

sin is -pie/2 to pie /2

cos is 0 to pie

tan is - pie /2 to pie /2

this is the only algorithm
