Undergrad Why does separation of variables work?
To solve a separable ODE like this I would simply multiply each side by dx and then integrate both sides. However, I know that it is only notational convenience that allows me to do this, and what's really going on is slightly more complicated. Take this DE for example...- Kaylee!

DiffEQ: Determining the largest interval of a solution
I'm multiplying both sides of the equation by secx, which has a domain of (-pi/2, pi/2), so that's the interval. Is this reasoning correct?- Kaylee!

DiffEQ: Determining the largest interval of a solution
The question is to determine the solution to the following 1st order linear DE, along with the largest interval the solution is valid on: cosx \frac{dy}{dx} + (sinx)y=1 Rewriting it shows it to be linear: \frac{dy}{dx} + (tanx)y = secx The intergrating factor is: e^{\int{tanx...- Kaylee!

Simplifying a rational expression
I've done a calculus problem. The LHS is my answer and the RHS is the answer in the book. \frac{2(x-1)^2}{(x^2-1)^2} = \frac{2}{(x+1)^2} What was done to simplify this equation?- Kaylee!

Solving an inverse trig equation
Homework Statement Solve for x arcsin(2x) + arccos(x) = \frac{\pi}{6} Homework Equations The Attempt at a Solution Subtracting arccos(x) from both sides and then taking the sine of both sides: 2x = sin\left[\frac{\pi}{6} - arccos(x)\right] Applying the difference angle...- Kaylee!
