Using Solve/FSolve for Multiple Trig Equations
Posted:
May 1, 2013 12:16 PM


Hello,
I am trying to solve for: y r p
in the following equations where I, J, K are known.
I = siny * sinr + cosy * sinp * cosr J = siny * cosr + cosy * sinp * sinr K = cosy * cosp
The code I have used is:
syms r p y i j k
S = solve(i == sin(y)*sin(r)+cos(y)*sin(p)*cos(r), j == sin(y)*cos(r)+cos(y)*sin(p)*sin(r), k == cos(y)*cos(p)) S.r S.p S.y
but I cannot seem to get a result.
Any help would be appreciated.
Thank you,
