Question

Please simplify this. Its answer is (3pi-10).

Answer 1

-30pi? i'm not sure if this is right tho hun...sorry

Answer 2

is all of it multiplication...

Answer 3

sine inverse is a function that gives back a number between -pi/2 and pi/2.
sine is a function whose domain is all real numbers, range between -1 and 1.
10 radians is coterminal with an angle in the 3rd quadrant....

so when we take arcsin (sin(10) we will not get back 10 radians but the angle in the 3rd quadrant (or 4th quadrant, because 3rd and 4th quadrants give negative sine)
therefore
arcsin (sin(10)) = 3pi - 10

Answer 4

oh :) ha
