The angle between two links of a robot arm is given by = at 3 + bt 2 + ct, where t is

The angle θ between two links of a robot arm is given by θ = at³ + bt² + ct, where t is the time during an 11.8-s cycle. If θ =19.0° for t = 1.00 s, θ = 30.9° for t = 3.00 s, and θ =19.8° for t = 5.00 s, find the equation θ = f(t). See Fig. 5.51.
