When calculating the gravity using a concial pendulum, we used the equation g = V_t²/R tanθ where the tangential velocity V_t = (0.63 x 0.01) m/s, radius R = (0.175 x1 0.01) m, and θ = 12.33^o. If we found theta with θ = tan^-1(0.175±0.01)m/(0.80±0.01)m, what is the absolute error of the angle and of the experimental value of gravity?
