Re: More trigonometric equations!!!

Thanks to everyone so far! You're really helping me learn this stuff
on my own + with a little guidance.

:)

Example 8. Solve the following equation for 0 degrees <= x <= 360
degrees:
cos^2(x) + 5sin(x)cos(x) = 3

I've tried dividing by A square of a trig function. I've also tried
substituting 3 = 3sin^2(x) + 3cos^2(x). But what I've found is that
the term involving sin(x)cos(x) is always present and prevents any
quadratic equation from appearing. What should I next try to do?
