Question

Solve the equation 3 sin x + 3 = 0
sinx = -1 what's next??

Answer 1

you can take the arcsin (sin^-1) of both sides and get the angle.-90

Answer 2

why do you have to take the arcsin?

Answer 3

because they're inverse functions. kinda like how taking the square root of x^2 gives you x.

Answer 4

oh okay, so if its -90 it should be 3pi/2 right?

Answer 5

in radians? Looks right.

Answer 6

thank you!!
