Let the position of a swinging pendulum in simple harmonic motion be given by s(t) = cos(t) + sin(t) where t measures time in seconds, and s measures position in centimeters. What is the tangent line to s(t) when t = 1.2 seconds? O a. y = 0.5697 x + 0.6108X O b. y = 1.2944 x + 0.6108 O c. y = -0.5697 x + 1.2533 O d. y = -0.5697 x + -0.6836 O e. y = -0.5697 x + 1.9780 Of. y = -0.5697 x + -0.1139
