1.The motion of a spring that is subject to a frictional force or a damping force (such as a shock absorber in a car) is often modeled by the product of an exponential function and a sine or cosine function. Suppose the equation of motion of a point on such a spring is

s(t) = 4e−1.9t sin 2πt

s is measured in centimeters and 
t in seconds. Find the velocity after 
t seconds.

2.Find the x-coordinates of all points on the curve 

f(x) = sin 2x − 2 sin x

 at which the tangent line is horizontal. (Enter your answers as a comma-separated list. Use 
n to represent any integer.)

3.ind an equation of the tangent line to the curve at the given point.

y = sin 9x + sin2 9x,(0, 0)
