Solution to Indeterminate set of equations

Question

回答： Nishant Gupta 2020-2-24

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?

I think it's impossible

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