wats up

hey I need help badly

4. anonymous

go for it

5. anonymous

I don't know how to simplify the equation above

6. anonymous

I will give you a medal if you can help

sorry :^( i don't know this yet

9. anonymous

please help me I need to understand this and I don't

Unclear what is wanted. $$3\sin(\theta) = \sin(\theta) - 1$$ Is that it? Can you solve... 3x = x-1?

11. anonymous

yes and yes

12. tkhunny

Okay, what is the solution to the little x-problem?

13. anonymous

x=-1/2

14. tkhunny

So, why wouldn't the solution to the original problem be $$\sin(\theta) = -1/2$$?

Right. And which is consistent with $$\sin(\theta) = -1/2$$?

No good. sine is positive in Quadrant I and sin(pi/2) = +1 If you have a negative sine, you should hang out in Quadrants III and IV.

then what is it then because I don't know
