Find two solutions to each equation in the interval 0

0< theta< 2pi

1) a) costheta = 0.15

theta = cos^-1(0.15) = 1.42 rad

theta = 2pi - 1.42 = 4.86 rad

b) tantheta = sqrt3

theta = pi/3

theta = pi+pi/3 = 4pi/3 rad

c) sin theta = 0.2

theta = sin^-1(0.2) = 0.201 rad

theta = pi - 0.201 = 2.94o rad
