(1 point) Let θ(in radians) be an acute angle in a right triangle and let xx and yy, respectively, be the lengths of the sides adjacent to and opposite θ. Suppose also that x and y vary with time.
At a certain instant x=8 units and is increasing at 1 unit/s, while y=5 and is decreasing at 1/3 units/s.
How fast is θ changing at that instant?

(1 point) Suppose a pendulum with length L (meters) has angle θ (radians) from the vertical. It can be shown that θ as a function of time satisfies the differential equation: ((d^2)θ)/(dt^2))+(g/L)sinθ=0 where g=9.8/sec is the acceleration due to gravity. For small values of θ we can use the approximation sin(θ)∼θ, and with that substitution, the differential equation becomes linear. A. Determine the equation of motion of a pendulum with length 0.5 meters and initial angle 0.5 radians and initial...
