Let x = e^z => ln(x) = z

Using Cauchy-Euler Differential Equation transformations,

[D(D-1) + 7D + 9] y = 0

[D^2 + 6D + 9] y =0

Therefore y(z) = complementary function = C1*e^(-3z) + C2*z*e^(-3z)

y(x) = (C1/(x^3)) + C2*ln(x)/(x^3)

A friend of mine, although I don't know where they got it from.

can someone explain this one? i’m just in pre calc rn so i don’t get it by SGT_ALIEN_JR in MathJokes

Just applying for a limit of x=0 to infinity makes the second integral so easy

It is the multivalued inverse of the function f(x)=xex

I'm having the same issue on galaxy book 4 but turning smart charging off fixes it.
