Question

How do I solve sin(x)=3 and sin(x)=1

Answer 1

what do you mean? separately?

Answer 2

Yeah. from 0-2pi

I understand that the inverse sine of 1 is 90. But since to domain of sine is from -1 to 1, how do I solve sin(x)=3?

Answer 3

This is in RADians?

Answer 4

Yeah.

Answer 5

so it would actually be pi/2 , not 90, right?

Answer 6

grd 12 advd functions right? I can't remember.

Answer 7

did this have a diagram of some sort? A unit circle?

Answer 8

No, the original question was: find all real solutions to the equation
sin^2(x)-4sin(x)+3=0 for 0<x<2pi.
and I solved that down to sin(x)=3 and sin(x)=1. Don't know what to do with that sin(x)=3.

Answer 9

maximum value of sin x =1, it can never =3

Answer 10

so the only real answer would be pi/2?

Answer 11

so, you take only sin x=1
yes!

Answer 12

THANK YOU BOTH!

Answer 13

welcome ^_^
