OpenStudy (alexwee123):

sin and arcsin cancel each other out

OpenStudy (anonymous):

so is it simply- -18/62 72*pi/63

OpenStudy (alexwee123):

wait im mistaken

OpenStudy (anonymous):

ohh

OpenStudy (alexwee123):

for sin(arcsin(-18/62)) you would find out the angle measure for arcsin(-18/62) then find the exact value for that angle

OpenStudy (alexwee123):

but ya they do cancel each other out
