Solve the equation (Enter your answers as a comma-separated list. Use as an integer constant. Enter your response in radians)
[math]2 cos^2(x) + 5 sin(x) = 4[/math]
[math]2 cos^2(x) + 5 sin(x) = 4[/math]
I have no idea what to do whatsoever. I know you have to use the quadratic formula i did that.
x [math]x = -5 + \sqrt{57} / 4[/math][math]x = -5 - \sqrt{57} / 4[/math]
I have the two x products now what do I do.
