    cos(pi theta) = -0.6 Eliminate the cosine from the left hand side. Take the inverse cosine of both sides: pi theta = 2.2143+2 pi n_1 for n_1 element Z or pi theta = 2 pi n_2-2.2143 for n_2 element Z Look at the first equation: Solve for theta. Divide both sides by pi: theta = 0.704833+2 n_1 for n_1 element Z or pi theta = 2 pi n_2-2.2143 for n_2 element Z Look at the second equation: Solve for theta. Divide both sides by pi: theta = 0.704833+2 n_1 for n_1 element Z or theta = 2 n_2-0.704833 for n_2 element Z

    Its n(sub 1)

    meaning, the (1) is on the side, below the (n). like the opposite of a squared or cubed.

    and it always equals (0).
