1. A pendulum is connected to a rope 3 m long, which is connected to a ceiling 4 m high. The angle between its widest swing and vertical hanging position is . If the pendulum swings out to its widest position in 2 seconds, model the height of the pendulum using a cosine function, considering vertical to be t= 0. 4] b. Determine a sine function that models this situation.
