How can I solve this issue? I have to keep the anwers in terms of R L and d, so I can't turn those into numerical values.
syms R L d
R = R;
L = L;
d = L/2;
syms x y fi teta beta gama
eq(1) = -L*cosd(teta) + x == 0;
eq(2) = -L*sind(teta) - L/2 + y == 0;
eq(3) = -0.5*L*cosd(teta)+d*cosd(fi) == 0;
eq(4) = -0.5*L*sind(teta) - d*sind(fi) + y == 0;
eq(5) = sind(gama) == (0.5*d)/R;
eq(6) = fi + gama + beta == 90;
sol = solve(eq,[x y fi teta beta gama])
Warning: Unable to find explicit solution. For options, see help.
sol = struct with fields:
x: [0×1 sym] y: [0×1 sym] fi: [0×1 sym] teta: [0×1 sym] beta: [0×1 sym] gama: [0×1 sym]
