Hi! I'd like to solve the following system of trigonometric equation: (R+r)*cos(gamma1) + r*cos(k*gamma1+alpha_0) == (R+r)*cos(gamma2) + r*cos(k* gamma2+alpha_1) (R+r)*cos(gamma1) + r*cos(k*gamma1+alpha_0) == (R+r)*cos(gamma2) + r*cos(k* gamma2+alpha_1)
where: gamma1, gamma2 = var('gamma1, gamma2') R=100 r=10 k=30 alpha_0 = 0 alpha_1 = pi/2 I tried the followin code: R = 100 r = 10 k = 30 alpha_0 = 0 alpha_1 = pi/2 gamma1, gamma2 = var('gamma1, gamma2') solve([(R+r)*cos(gamma1) + r*cos(k*gamma1+alpha_0) - (R+r)*cos(gamma2) + r* cos(k*gamma2+alpha_1), (R+r)*cos(gamma1) + r*cos(k*gamma1+alpha_0) - (R+r)* cos(gamma2) + r*cos(k*gamma2+alpha_1)], (gamma1, gamma2)) Sympy solve it too long and I can't wait for result.
