how would i find the degrees of cos x= 3/2
if (0 <or= theta < 360)? i've tried putting it in my calculator with cosine^-1 but im just getting err:domain. Please help!

The cosine function only goes from -1 to +1.
There is no solution to cos x = 3/2.

thank you!

    solve the equation: 4cos2*theta + 3cos*theta + 3 = 0 for values between 0 and 180 degrees If that is cosine squared in the first term, you have a quadratic equation. Normally cosine squared would be written in ASCII as cos^2 Theta.
