# Need Help to Solve for This Equation

## Need Help to Solve for This Equation

(OP)
I need help solving this equation for c1,c2,p1,p2:
(2 4)T=c1.(0.732 1)T.sinp1+c2*(-2.732 1)T.sinp2
(0 0)T=w1.c1(0.732 1)T.cosp1+w2.c2.(-2.732 1)T.cosp2

T: Transpose
(.. ..)T: vector
w1 and w2 are known

Any help is greatly appreciated.

Regards

### RE: Need Help to Solve for This Equation

(OP)
I solved the equation using MathCad's non-linear equqation solver. I only had to describe a relationship between sinp1 and cosp1 using sinp1^2+cosp1^2=1
I wrote cosp1 in terms of sinp1 and used sinp1 as an ordinary variable like p.
Then rewrite the equations and solved. I also verified my solution.
