Numerical solution of a system of nonlinear equations

Postby amindanial » Sat Oct 22, 2016 8:55 am

Classpad 400 cannot numerically solve the following system of equations:
((1 / 24 * π) * cos(((1 / 180 * θ1) * π))) + λ=0
((7 / 120 * π) * cos(((1 / 180 * θ2) * π))) + λ=0
((7 / 72 * π) * cos(((1 / 180 * θ3) * π))) + λ=0
θ1 + θ2 + θ3 - 360=0
It gives insufficient memory

Does anyone have an idea how to do it on classpad 400?
Is there a hope to get a function like fsolve that takes an initial guess of the solution?
HP prime has such powerful function.
Casio has to add such function.
