Question

Trig Problem Help: 2cos(θ)+√(3)=0
(See attached)

Answer 1

Well to start off with, isolate cos(theta) all by itself.

Answer 2

how do i do that?

Answer 3

Well, it's inverse operations. You do it the same way that you would get x by itself in algebra. Like if I had 2x - 4 = 5. You would add 4 to both sides and divide by 2. It's the same thing with this, just act like cos(theta) is an x. That make any sense?

Answer 4

That makes sense actually
I got this answer i'm not sure if its right:
θ= 5π/6 + 2πn or θ= 7π/6 + 2πn

Answer 5

That works for me :P

Answer 6

thats the right answer?

Answer 7

Yep xD Looks good to me.

Answer 8

ok thanks
