Solving trigonometric equations
I need help on solving these problems within specific intervals. I am having trouble solving for x the most. Any help is again appreciated.
5-7sin x = 2cos^2 x x = [ -360, 450 degrees ]
2csc^2 x = 3cot^2 x – 1 x = [ 0, 2pi ]
This is just a sampling of my homework, but it will help me a ton if someone can go through these correctly.
