(x-(cos(alpha1)*(la*cos(theta1)+R)))^2 + (y-(-(R+la*cos(theta1))*sin(alpha1)))^2 + (z-(-la*sin(theta1)))^2 =lb^2; (x-(cos(alpha2)*(la*cos(theta2)+R)))^2 + (y-(-(R+la*cos(theta2))*sin(alpha2)))^2 + (z-(-la*sin(theta2)))^2 =lb^2; (x-(cos(alpha2)*(la*cos(theta3)+R)))^2 + (y-(-(R+la*cos(theta3))*sin(alpha2)))^2 + (z-(-la*sin(theta3)))^2=lb^2;

x1+x2=1
0.718+y2 = 1
x1*P"= 0.718*86.8
x2*P2" = y2* 86.8

Step 1: Express your equations into an Augmented Matrix where each equation represents a row of that matrix (excluding the answers/ the value beyond "=" sign.), assign the matrix to a variable. Let say A.
Step 2: Form a column matrix of the answers/ values beyond the "=" sign. Assign the column matrix to another variable B.
Step 3: Compute the solution by 'linsolve()' function OR sipmly A\B=inverse(A)*B
Solution=linsolve(A,B)
