Question

Arcsin(sin(3pi))

Answer 1

Sin 3pi is 0. Thus Arc sin(0) is 0 or in reallity any mulitpl of pi

Answer 2

arcsin(sin3pi)
arcsin(sinx) is x only when x lies between -pi/2 to pi/2
sin 3pi=0
arcsin (0)=0
so 0 is the answer
remembert the range of arcsin is -pi/2 to pi/2

Answer 3

Answer 5

i dont understand how acrsin(sin(3pi))=3pi=0 . its said that the range of acrsin is -pi/2<y<pi/2 which lies between quadrants 1 and 4. if 3pi lies in the x-axis between quadrants 2 and 3, then how is 3pi in the range of arcsin? thus how is the answer 0 ? please help
