Oh, starting with a JEE Advanced math problem for 2025. I'm curious to see what kind of question they've picked to kick things off.
Okay, so the initial setup is to deal with a differential equation. The strategy of dividing by x² to make it homogeneous is a classic approach for these types of problems. It really simplifies the structure.
This substitution y/x = v is the key move to transform the equation. I like how they're clearly showing the steps for the derivative dy/dx, which is crucial for the next stage of substitution.

The video begins by presenting a JEE Advanced mathematics problem involving a differential equation [0:00]. The core of the initial approach involves transforming the given differential equation into a homogeneous form by dividing by x² [0:24]. This allows for the substitution of y/x with a new variable 'v', leading to dy/dx = v + x(dv/dx) [0:49]. This substitution simplifies the equation to v + x(dv/dx) + v = 1 + v², which can be rearranged as x(dv/dx) = 1 + v² - 2v [1:14].
