Hello, Stealth!
I'll make up my own instructions . . .
We're expected to know the identity: .Solve for
So the left side is: .
The equation becomes: .
Factor: .
And we have: .
Hey everybody.
I got this math assignment and I've been trying to work this problem but I have NO idea how.
Can anyone help?:
[tex]squareroot[1-cos2theta] = 2sinsqaredtheta/MATH]
I apologize in advance if the math button didn't work...
I'm still new to this forum!
Any help is appreciated,
Stealth
Hi! I noticed something when I worked it out another way!:
We're expected to know the identity: .
So the left side is: .
On the squareroot(2) part, would that be a plus/minus squareroot(2) because then wouldn't we also have the solutions of 5pi/4, and 7pi/4?
The equation becomes: .
