I have two equations i am trying to solve. I used the next small code but I received an error message.
the 2 equations: r2*sind(theta2)-r3*sind(theta3)-r4=0 r1+r2*cosd(theta2)-r3*cosd(theta3)=0
Known: r2=3; r3=3.927; r4=0.335; theta2=10;
Code: lear all clc syms theta3 sind(theta3) r1 r2=3; r3=3.927; r4=0.335; theta2=10; t=(r2*sind(theta2)-r3*sind(theta3)-r4); theta3=subs(char(solve(t,theta3))); tt=vpa(r1+r2*cosd(theta2)-r3*cosd(theta3)); r1=subs(char(solve(tt,r1))); theta3 r1
Error: Error using mupadengine/feval (line 157) MuPAD error: Error: Cannot differentiate equation. [numeric::fsolve]
