Thread: General Solutions to Equations...

How can I find the general solutions to the following equations where 0 < x < 2pi?

2cos^2x + cosx = 1

2tanx + square root of 12 = 0

Thanks.

set each factor = 0 and solve for cosx ... solutions for x will be unit circle values


2tanx + square root of 12 = 0





look for solutions on your unit circle
