WebFeb 1, 2012 · 158. 0. susskind_leon said: A function is complex differentiable if their partial derivatives for u and v exist and they satisfy the C-R-eq. Since the p.d. for u do not exist, f (z) is not complex differentiable (in z=0). This means that f (z) is not holomorphic in z=0. So just take the limit of f (z) approaching from the x and y-axis to show ...

WebWe first show that \lim _ { (x, y) \rightarrow (0,0)} f (x, y) lim(x,y)→(0,0)f (x,y) does not exist, so that f f cannot be continuous at (0,0) (0,0). To show that, we first let (x, y) \rightarrow (0,0) (x,y) → (0,0) along the line y=x y = x. Then \frac {x y} {x^ {2}+y^ {2}}=\frac {x^ {2}} {x^ {2}+x^ {2}}=\frac {1} {2} x2+y2xy = x2+x2x2 = 21, WebIf f (x) is not differentiable at x₀, then you can find f' (x) for x < x₀ (the left piece) and f' (x) for x > x₀ (the right piece). f' (x) is not defined at x = x₀. For example, f (x) = x - 3 is defined and continuous for all real numbers x. It is differentiable for all x < 3 or x > 3, but not differentiable at x = 3. corporate trainers in lahore
