What values for theta( 0 <= theta <= 2pi) satisfy the equations?
1. 4cos(theta) + 1 = 2cos(theta);
2. cos(theta) - tan(theta)cos(theta)= 0
------------------------------------------------------- 

1.   =   --->   = -1  --->   =   --->   =   and/or   = .  

    No other solutions in the given interval.


2.   =   --->   = 1  --->   =   and/or   = .

    No other solutions in the given interval.
