Solution to Indeterminate set of equations

9 views (last 30 days)
I have 10 variable and 5 equations describing them.
For Eg. (e,f,g,h,k,m are all angles)
syms a b c d e f g h k m
unkowns = [a b c d e f g h k m]
x=10
y=5
equations=[a+b+k-pi==0,
c+d+m-pi==0,
a*sin(e)+b*sin(g)-x==0,
a*cos(e)+d*cos(f)-y/2==0,
b*cos(g)+c*cos(h)-y/2==0]
solution=vpasolve(equation,unknowns)
However, when I run this, I do not get solutions for the variables. The function returns empty solutions.
Is there an alternative procedure to solve such indeterminate equations?

You will get the solution, just use the proper variable names. Either use equation everywhere or equations. Same with unknowns.
