is there another way to find the particular solution without doing the wronskian? i did the wronskian of cos(t), sin(t), tcos(t), tsin(t) and it ended up being zero, which isn't supposed to happen. so is there another way of solving the part. solution?
Homework Statement
Use the method of variation of parameters to determine the general solution of the given differential equation: y^(4) + 2y'' + y = sin(t)
Homework Equations
characteristic equation is factored down to (r^2 + 1)^2, so r = +/- i. this gives the general solution to be...
[SOLVED] Period of a satellite
1. Given: G = 6.67 x 10^-11 N m^2/ kg^2
The acceleration of gravity on the surface of a planet of radius R = 4910 km is 11.8 m/s^2. What is the period T of a satellite in circular h = 8445.2 km above the surface? Answer in units of s.
