Question

how do you find the exact value of sin-1(sin pi/8)

Answer 1

pls put the brackets properly..

Answer 2

Put it in the calculator. They are easy enough to understand Prawal.... Sin^-1 (sin(pi/8))
This would be .3926990817

Answer 3

hmm ...
inverse..
its pi/8
u dont even need a calculator..

Answer 4

\[f^{-1}(f(x)) = x \]
the basic law of calculus..

Answer 5

Alright Mr. Need the brackets proper....No need to put others down to make yourself feel better..k ty bye

Answer 6

:\

Answer 7

"the basic law of calculus.." Maybe said person hasn't gotten to calculus and might even be just doing trigometric functions...did you think of that?... There are so many teaching methods out there and so many subjects that use sin...can you really predict that person already knew that?

Answer 8

haha thats why my username is trig short for trigonometry

Answer 9

thanks for the help Mpost

Answer 10

No problem

Answer 11

that is the basic law u'll obviously find it every buk with trignometry on the very first page where intro about inverse function is given...

and that thing is a bit logical too..

Answer 12

OBVIOUSLY will find it in EVERY book with trigonmetry.....Quite sure are you? ..That is what we call impossible to know. And yes it might be logical but if you haven't learned it..how would you know it whether or not is is logical? ....Next time just don't assume Prawal and don't act like something is completely obvious and you should already know it. Okay goodbye now.
