Pre Calculus and Trig Help

[From: ] [author: ] [Date: 12-06-27] [Hit: ]
2--0.the arcsin function will take it one way but the sin on the outside will bring it right back to -0.......
Use the properties of inverse functions to evaluate the expression.
sin[arcsin(-0.2)] can anyone please help?

-
sin(sin^-1(-0.2)) = -0.2

there is no manipulation of the angle necessary because all domain and range issues are satisfied

-
It is -0.2. Think of it like the sine and arc sine cancle each other out sine they are opposite leaving only the -0.2

-
-0.2

the arcsin function will take it one way but the sin on the outside will bring it right back to -0.2
