I have a really hard time using Mathlab solving this problem
Pleas help me find T1 T2 T3 alfa beta and gramma
-T1cos(alfa)+T2cos(beta)=0 (1)
-50+T1sin(alfa)+T2sin(beta) =0 (2)
- T2cos(beta)+T3cos(gramma) =0(3)
-100+T2sin(beta)++T3sin(gramma) =0 (4)
3.6cos(alfa)+ + 3.6cos(beta) + 3.6cos(gramma) = 10.5 (5)
sin(alfa)+ + sin(beta) = sin(gramma) (6)

sol=solve(-T1*cos(alfa)+T2*cos(beta)==0, -50+T1*sin(alfa)+T2*sin(beta) ==0,- T2*cos(beta)+T3*cos(gramma) ==0,-100+T2*sin(beta)+T3*sin(gramma) ==0, 3.6*cos(alfa)+ 3.6*cos(beta) + 3.6*cos(gramma) == 10.5, sin(alfa)+ sin(beta) == sin(gramma) )
This willt take a long time to solve because of the sines and cosines. Also it should be gamma, not gramma.

It shown undefined variable Undefined function or variable 'T1'.
