Given the second order non-homogeneous linear differential equation y+2y-3y 3 ex+ 4 cos x, (notation e^x= exp(x) = "e raised to the x power, cos x="cosine of x") find a particular solution yp of the non-homogeneous equation.
Ratios
A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.
Trigonometric Ratios
Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
For the PI how do I use the inverse operator when I write
3e^x/(1+3)(D-1)+4cosx/(D^2+2D-3)
3/4e^x/D-1+4cosx/-1+2D-3
3/4 x!/1! e^x + 4 cos x/-4+2D=3/4xe^x+2cosx/D-2
Using PI of 1/D-alphaQ = e^alpha x integrate e^-alpha Qdx.
how do I proceed from there the steps for finding PI answers the full solution
