We already know that this function is continuous at every ˉx ∈ (0, 1). We will show that f is not uniformly continuous on (0, 1). Let ε = 2 and δ > 0. Set δ0 = min {δ / 2, 1 / 4}, x = δ0, and y = 2δ0. Then x, y ∈ (0, 1) and x − y = δ0 < δ, but.

WitrynaAnswer (1 of 3): For [f(x)] to be continuous, f(x) must lie between two consecutive integers for all values of x. Now at x=0, xsinx takes value 0 and at x=π\2 it takes value π\2 which is greater than 1. So there must be a break in the curve of [xsinx] at some point between 0 and π\2. Hence, [xsin... identity biology

WitrynaThe fourth derivative of sinx also comes from an application of the constant multiple rule: d4 dx4 sinx = d dx (¡cosx) = ¡ d dx cosx = ¡(¡sinx) = sinx: So the fourth derivative of sinx is itself. That means that its ﬁfth derivative is cosx, its sixth derivative is ¡sinx, and so on: the higher derivatives of sinx are period in yet another ... Witryna5 years ago. Sal was trying to prove that the limit of sin x/x as x approaches zero. To prove this, we'd need to consider values of x approaching 0 from both the positive and the negative side. So, for the sake of simplicity, he cares about the values of x approaching 0 in the interval (-pi/2, pi/2), which approach 0 from both the negative (-pi ...
