If two sides and the included angle of a triangle are given, the Law of _______ is used to solve the triangle .
What do you do first if you are asked to solve a triangle and are given two sides and the angle opposite one of them?
an object attached to a coiled spring is pulled down a distance a from its rest position and then released. Assuming that the motion is simple harmonic with period T, write an equation that relates the displacement d of the object from its rest position after t seconds. Also assume that the positive direction of the motion is up:
