In mathematics, an ordinary differential equation (ODE) is a differential equation containing one or more functions of one independent variable and the derivatives of those functions. The term ordinary is used in contrast with the term partial differential equation which may be with respect to more than one independent variable.
I have a "Solve the initial value problem" It is:
y'' + y = 2cosx - 3sinx
I know how to do everything except for get yp. I know it has to be something so when i substitute yp into the left hand side of the equation, i get the right hand side, 2cosx - 3sinx.
By this definition i would...
Here is the problem...
Find the exponential function y=Ce^{kt} that passes through the points (0,4) and (5,1/2).
Just by looking at the problem, I know...
y=4e^{\frac{-3x \ln{2}}{5}}
...works, but how do you actually work out the problem? I've done it before given a point and the...
