Question

Find a solution with theta in radians (of possible)

Answer 1

1.
     tan(theta)947     theta = arc tan(947)     theta = 1.56974
3.
    3 cos(theta)=0.714    3 cos(theta)/3=0.714/3    theta = arc cos(0.238)    theta = 1.33049
5.
     tan(5(theta))+7 = -0.241     tan(5(theta)) = -7.241     5(theta) = arc tan(-7.241)     theta = -1.433562/5     theta = -0.286712
