find the values of the inverse function in radians for arcsin(0.65).
a.0.71+2pi n and -0.71+2pi n
b.0.71+2pi n and -3.85+2pi n
its either one of these but i dont understand the second part to the answer i got the first part

i think this is strictly a calculator question....
just plug that problem into your calculator but make sure your calculator is in RADIAN mode....

anonymous · Answer

i dont know how to use the calculator for these problems.

anonymous · Answer

arcsin is that button on your calculator with "$\large sin^{-1} $"....

anonymous · Answer

i got the first part of the answer but im not sure how to get the second part

anonymous · Answer

OIC... you mean after the "and" in the choices above..... ????

anonymous · Answer

yes

anonymous · Answer

the RANGE of arcsin is [-pi/2, pi/2] or about [-1.57, 1.57]...
since -3.85 is not in the range, i'd say your answer is the first one...
