If three sides of a triangle are given, the Law of _________ is used to solve the triangle.
A special case of the Law of Cosines is the Pythagorean theorem.
The hypotenuse of a right triangle is 5 inches. If one leg is 2 inches, find the degree measure of each angle.
Find the area of the triangle. Round answer to two decimal places.
An object of mass m (in grams) attached to a coiled spring with damping factor b (in grams per second) is pulled down a distance a (in centimeters) from its rest position and then released. Assume that the positive direction of the motion is up and the period is T (in seconds) under simple harmonic motion.
(a) Develop a model that relates the distance d of the object from its rest position after t seconds.
(b) Graph the equation found in part (a) for 5 oscillations using a graphing utility.
