hi, i just post here my script

syms theta1 theta2 theta3 theta5 theta6 r1 r2 r21 r3 r5 r6 r7 r4
[theta2,theta3,theta5,theta6] = solve('r1*cos(theta1)+r21*cos(theta2)+r5*cos(theta5)+r6*cos(theta6)-r4=0', 'r1*sin(theta1)+r21*sin(theta2)+r5*sin(theta5)+r6*sin(theta6)=0', 'r1*cos(theta1)+r2*cos(theta2)+r3*cos(theta3)-r7-r4 = 0','r1*sin(theta1)+r2*sin(theta2)+r3*sin(theta3)=0',theta2,theta3,theta5,theta6);

now i want to solve this system of trigonometric equations so that
theta2,theta3,theta5,theta6 are a function of theta1 !

but matlab give me the error "Warning: Explicit solution could not be found"
i think because i use syms ?!

who help me ??
Thank a lot !
