There are many cases where you will want to find the time average of the square of a sinusoidal (or cosinusoidal) wave. An example would be calculating the average energy in the wave. Suppose I have two waves: E1 = Acos(kx − ωt + φ) E2 = B cos(kx − ωt + θ) where A and B (both real) are the amplitudes and φ and θ are the phases of the waves. They have the same wave vector k and angular frequency ω. (Assume the field directions are the same too.) 1 a. Calculate the time average of the product of E1 with E2 which is defined as E1E2 = 1 T T 0 E1E2 dt where T is a time interval long compared to the period of the wave.

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
