Question

can someone find the derivative of (x^2)cos(1/x)+e^2

Answer 1

youre gonna need the chain rule and product rule for the first part.\[\frac{d}{dx} (x^{2}\cos(\frac{1}{x})) = 2xcos(\frac{1}{x})+x^{2}(-\sin(\frac{1}{x}))(-\frac{1}{x^{2}})\]
Then you gotta simplify

Answer 2

cos(1/x)(2x)+(x^2)(sin(1/x)(x^-2) and the e cancles cause its a constant
