Question 1

Which of the following equations is a linear PDE?

\\left( \\frac{\\partial u}{\\partial x} \\right)^2 + \\frac{\\partial u}{\\partial y} = 0
\\frac{\\partial u}{\\partial t} + k \\frac{\\partial^2 u}{\\partial x^2} = 0
2u^2 + \\frac{\\partial u}{\\partial x} = 0

💡 Hint: Look for powers that are only one.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Devise a nonlinear PDE that incorporates both x and y derivatives and explain how it fits the definition of nonlinear.

💡 Hint: Make sure one term is a product of derivatives or powers.

Challenge 2 Hard

Explain the significance of superposition in linear PDEs and why it doesn’t apply to nonlinear PDEs with an example.

💡 Hint: Think of concrete examples showing different behaviors in solutions.
