Find the general solution of the given differential equation. dy/dx = 9yy(x) = ?

Mathematics

Answer:

See answer below

Step-by-step explanation:

This is a separable equation, so we solve it like this:

\frac{dy}{y}=9dx \implies (\ln(y))'=9dx \implies ln(y)=9x+c \implies y=e^{9x+c} \implies y=ke^{9x}

Then y(x)=ke^{9x} for any constant k (this is the general solution). This solution is defined in (-∞,∞) (there are no singularities) and when x tends to infinity, no terms of the solution vanish, hence there are no transient terms.

Ay/b-by/a=a^2-b^2. find value of y
klemol [59]
We can actually undsitribute the y

y( \frac{a}{b}- \frac{b}{a})=a^2-b^2
divide both sides by ( \frac{a}{b}- \frac{b}{a})
y= \frac{a^2-b^2}{ \frac{a}{b}-  \frac{b}{a}  }
times the right side by (ab/ab)
y= \frac{ab(a^2-b^2)}{ a^2- b^2  }
y=ab
