Solve the problem.When the angular displacement ? of a pendulum is small (less than about 6°), the pendulum moves with simple harmonic motion closely approximated by src="https://sciemce.com/media/4/ppg__tttt0610191332__f1q26g5.jpg" alt="" style="vertical-align: -4.0px;" /> and 
where 
g is the acceleration due to gravity, and l is the length of the pendulum. Find ? as a function of time (in sec) if 
when 
A. ? = -2 cos 1.4t + 0.1 sin 1.4t
B. ? = 0.1 cos 1.4t
C. ? = -2 sin 1.4t + 0.2 cos 1.4t
D. ? = -2 sin 1.4t + 0.1 cos 1.4t
