Hello all, just have a quick question I'm hoping someone could answer.
I have a system of equations:
r5 Cos[theta5] + r6 Cos[theta6]+ r7 Cos[theta7] + r8 Cos[theta8] - r4 Cos[theta4] == 0 ;
r5 Sin[theta5] + r6 Sin[theta6] + r7 Sin[theta7] + r8 Sin[theta8] - r4 Sin[theta4] == 0;
Everything is known except for theta5 and theta6, so I have two equations and two unknowns.
How would one go about solving for theta5 and theta6 using Mathematica?
I would appreciate any help
