Prove sin 1/x is differentiable
WebbMath Advanced Math Exercise (4) ² = 1: Show that the cycloid C defined via C (x, y) = -2r-y y [x (0)=r (0-sin (0))] v (0) = r (1-cos (0) satisfies the differential equation show that our cycloid from Exercise 1 satisfies the differential equation and hence is a solution to the tautochrone problem. WebbDid you mean the derivative of ln(u)? Because the derivative of ln(x) is 1/x, if we have the derivative of ln(u), where u is some polynomial, then we must use u-substitution, which says that d/dx[f(g(x))] = f'(g(x))*g'(x) If we do that for our ln expression, we get: d/dx[ln(u)] …

Webb20 juni 2024 · Using first principle, when we try to check the differentiability of $x^2\sin(1/x)$ at $x= 0$,we get 0. But if we differentiate the function first, and then try to find differentiability at x=0,we we find it's not differentiable. I have encountered similar … WebbCorrect option is C) f(x)=∣x∣sinx={−xsinx,x<0xsinx,x≥0. f(x)={−sinx−xcosx,x<0sinx+xcosx,x≥0. Clearly at x=0, L.H.D =0= R.H.D. Hence f(x) is …

Webb9 maj 2016 · 1 Answer sente May 9, 2016 The function, as given, is not continuous at 0 as 0sin( 1 0) is not defined. However, we may make a slight modification to make the function continuous, defining f (x) as f (x) = {xsin(1 x) if x ≠ 0 0 if x = 0 We will proceed using this modified function. Webb7 sep. 2024 · Let f be a function. The derivative function, denoted by f ′, is the function whose domain consists of those values of x such that the following limit exists: f ′ (x) = lim h → 0f(x + h) − f(x) h. A function f(x) is said to be differentiable at a if f ′ (a) exists. More generally, a function is said to be differentiable on S if it is ...
