Class 10th mathmatics trigonometry important questions Requirements:

Define the function f(x)={x2sin?(1×2),x0,0,x=0.f(x)=begin{cases}x^2sin!left(dfrac{1}{x^2}right), & xneq 0,\[6pt]0, & x=0.end{cases}f(x)=x2sin(x21),0,x=0,x=0. (a) Prove that f(x)f(x)f(x) is continuous at x=0x=0x=0. (b) Determine whether f(x)f(x)f(x) is differentiable at x=0x=0x=0. If so, find f(0)f'(0)f(0). (c) Find an explicit formula for f(x)f'(x)f(x) for x0xneq 0x=0. (d) Decide whether f(x)f'(x)f(x) is bounded on any neighborhood of x=0x=0x=0. (e) Determine whether f(x)f'(x)f(x) is…
