sir at the last example is it y_p=......+B.cos(2x) or B.cos(4x)

yeah I messed up, it's the one with cos(4x)

I'm struggling to understand this problem y"+y=3sin(2t)+tcos(2t) . Can you please please explain the particular equation of this problem? Also it would be great if you explain the full problem. Thank you in advance the math sorcerer. I understand your lecture clearly.

good evening, on examples of where we can use this method you said no to 1/x + sec(x) function, even if we write sec(x) as 1/cos(x) and move it to numerator would that be still a no since it is on denominator?
@TheMathSorcerer5 жыл бұрын
correct,that would still be a no

If g(x) = x^3, does that mean the Yp = Ax^3 + Bx^2 + Cx + D?

You write it as polynomial with constants as coefficients and variable of descending power added up

Once again, don't mind me, I just be jumping around to stuff my professor hand waved a little much for me at the beginning of the first lecture, and I'll be taking many spammy notes in the comment section.

Okay, so when the RHS has a nice derivative and a nice integral we can use this, got it.

yp is a value y can take, so we plug that into the DE, we plug in its derivatives as well. Okay honestly, this isn't hard, I'm just psyching myself out.
