e modeled by a trigonometric function.
The modeling function has period 0.80.80, point, 8 seconds, amplitude 6 \text{ cm}6 cm6, start text, space, c, m, end text, and midline H = 15 \text{ cm}H=15 cmH, equals, 15, start text, space, c, m, end text. At time t = 0.2t=0.2t, equals, 0, point, 2, the bob is at its midline, moving towards the wall.
Find the formula of the trigonometric function that models the distance HHH between the bob and the wall after ttt seconds. Define the function using radians.
