solve for theta 2cos^2theta 3costheta-1=0
Added by D. Chance D.
Step 1
We can do this by factoring out a cos(theta) from the first two terms: 2cos^2(theta) - 3cos(theta) - 1 = 0 This equation is a quadratic equation in terms of cos(theta). We can solve it by using the quadratic formula: cos(theta) = [3 ± sqrt((3)^2 - Show more…
