Watch as we derive the derivative of f(x)=x^2*sin(1/x), including the challenging part of handling the derivative at x=0, where the function is not differentiable. But we don't stop there - we also introduce the squeeze theorem, a powerful tool to evaluate limits, to further deepen our understanding of calculus. This video is perfect for anyone looking to enhance their calculus knowledge and master the fundamental concepts of derivatives.
