I know most of the trigonometric identies, but I'm still stuck on how to solve it.Solve the equation for .
This is how far I've gotten.
.Solve the equation for
Same problem here. I get stuck and can't solve the problem. Help?
Applying the zero product property...
Solve these (don't forget that you'll get multiple solutions like above with the cosine - then limit them to your interval).
Then for the other one of the first equation, I got , which would be ...would that be right? Do i have to add the ?
And for the second problem, I got ...and then I'm stuck as I can't seem to figure it out. Help?
