This data can be summarized by the formula where k is the decay rate of the rabbits. The goal of this problem is to derive an estimate for the decay rate. You should minimize the quantity with respect to k. Make a plot of your best fit curve and also the data points and visually inspect how good it is. When a crankshaft of throw radius r remains connected via a rigid rod of length L to a piston much as in the diagram the law of cosines assures us that P where x is the horizontal distance OP from the main bearing to the sliding piston.
Light travels between two points along the path that requires the least time.
Let the velocity of light in two adjoining media such as air and water be v 1 and v 2 . Calculate the path of a light ray which travels from point P in one medium to point Q in the other.
