Solve: tan(sin^−1))

OpenStudy (aravindg):

tan(sin^−1 x ))= ?

OpenStudy (anonymous):

There is no X. Everytime I tried to put that x in the answer I got wasn't one of the choices.

OpenStudy (aravindg):

have you learnt inverse trigonometry ?

OpenStudy (anonymous):

Not very well. I'm dyslexic so math is really hard for me

OpenStudy (aravindg):

oh ok I can help you :)

OpenStudy (aravindg):

Please wait

OpenStudy (anonymous):

Okay, thanks

OpenStudy (aravindg):

Well do you have options for this question ?

OpenStudy (anonymous):

Yeah, the options are: A. 1 B. 0 C. -1 D. undefined

OpenStudy (anonymous):

Is it just undefined?

OpenStudy (zarkon):

looks like you are not writing the entire problem

OpenStudy (aravindg):

ya something seems missing

OpenStudy (anonymous):

This help?

OpenStudy (aravindg):

Better :)

OpenStudy (aravindg):

ok for these problems we move from inside out

OpenStudy (aravindg):

look the inside function is sin^-1 -1 so we will deal with that first

OpenStudy (aravindg):

Do you know how to find sin^-1 -1 ?

OpenStudy (anonymous):

No:/

OpenStudy (anonymous):

Well, do I have to do it with a calculator?

OpenStudy (aravindg):

well if you are allowed to do it proceed

OpenStudy (aravindg):

If you need to do it manually you need to learn some rules

OpenStudy (anonymous):

My calculator keeps telling me syntax error, not sure what I'm doing wrong. I hit the sin^1 key and then minus one

OpenStudy (anonymous):

sin^-1*
