solve each equation on the internal 0 is greater than equal to theta less than 2pie.
10) (cot theta +1)(csc theta -1/2) = 0
Hint: . Now use either the known period of or the symmetry of the unit circle to find the second value of .
You're expected to know these things. If you don't, then you should be reviewing earlier work on how to solve basic trig equations involving sin, cos and tan instead of attempting to solve the equations you've been posting.
