Since lnx is one-to-one, then ex+y = ex ·ey. 1 = e0 = ex+(−x) = ex ·e−x ⇒ e−x = 1 ex ex−y = ex+(−y) = ex ·e−y = ex · 1 ey ex ey • For r = m ∈ N, emx = e z }|m { x+···+x = z }|m { ex ···ex = (ex)m. • For r = 1 n, n ∈ N and n 6= 0, ex = e n n x = e 1 nx n ⇒ e n x = (ex) 1. • For r rational, let r = m n, m, n ∈ N Mar 06, 2021 lim (x;y)→(0;0) @2f @x@y (x;y)= lim (x;y)→(0;0) „ 8(x2 −y2)x2y2 +(x2 −y2)(x2 +y2)2 (x2 +y2)3 ‚: This limit doesn’t exist, (e.g. using polar coordinates), and the func-tion is not C2. 3.2.2: L∶R2 → R linear, so L(x;y)=ax+by: (a) Find the rst-order Taylor approximation for L: Since Lis linear, and since the rst-order Nov 24, 2016 Homework 3 Solutions Math 171, Spring 2010 Please send corrections to henrya@math.stanford.edu 17.4.

lim z!1 ez is not de ned because it has di erent values if we go to in nity in di erent directions, e.g. we have ez= exeiy and lim x!1 exeiy= 0 lim x!+1 exeiy= 1 lim y!+1 exeiy is not de ned, since xis constant, so exeiy loops in a circle inde nitely. Example 2.7. Show lim z!1 zn= 1(for na positive integer).

In this case, R is a topological space and any function of the form f: X → Y with X, Y⊆ R is subject to the topological definition of a limit. Note that with this topological definition, it is easy to define infinite limits at finite points, which have not been defined above in the metric sense.

3 Apr 2020 Euler and Runga-Kutta methods are used for computing y over a lim- xy dx e.. y (0) 1 for y at x 0.1, x 0.2 and x 0.3. Solution: Taylor's series solution up to the term in hr where r differs from method to. xy'' + y = 0 y(0) = 1, y'(0) = 2 P(x)y'' + Q(x)y' + R(x)y = 0 (x sin x)y'' + (cos x)y' + ex y = 0 This limit is undefined hence the singularity at x = 0 is irregular. h is +1 if h > 0 and −1 if h < 0.

There is a notion of lim sup and lim inf for functions defined on a metric space whose relationship to limits of real-valued functions mirrors that of the relation between the lim sup, lim inf, and the limit of a real sequence. Take metric spaces X and Y, a subspace E contained in X, and a function f : E → Y. Define, for any limit point a of E, lim x→0 ex − 1 − x x2 = lim x→0 ex − 1 2x = lim x→0 ex 2 = 1 2 L’Hˆopital’s Rule works in another case besides 0/0 forms. It works on expressions of the form ±∞/ ±∞; e.g., lim x→∞ ex x is of the form ∞/∞ and (ex)0 (x)0 = ex 1. Since lim x→∞ ex 1 = ∞, it follows that lim x→∞ ex x = ∞.
