I was confused with this.
I have to find all the solutions for 0<x<360o if sinethreex=(square root2)/2
So I was confused with this.
I know (square root2)/2 occurs in 45o, also pi/4
Then it occurs at 135o, also 3pi/4
I'm not sure if these 2 are the correct solutions.
I understand where sin (the y coordinate) is (sqrt2)/2
But I'm not sure what the sinethreex means.
Can someone explain.
