ABSTRACT Content deﬁnition, proof of Taylor’s Theorem, nth derivative test for stationary points, Maclaurin series, basic Maclaurin series In this Note, we look at a Theorem which plays a key role in mathematical analysis and in many other areas such as numerical analysis. Taylor polynomials look a little ugly, but if you break them down into small steps, it’s actually a fast way to approximate a function. We also derive some well known formulas for Taylor series of e^x , cos(x) and sin(x) around x=0. The trick is to write f(x0+ x;y0+ y) = F(1) with F(t) = f(x0+t x;y0+t y) and think of x0, y0, x and y as constants so that F is a function of the single variable t. /Subtype/Link/A<> xn = 1+x+ x2 2 + x3 6 + x4 24 +:::; x 2R 2: cosx = X1 n=0 ( 41)n (2n)! /A << /S /GoTo /D (Navigation17) >> >> endobj /Type /Annot /Rect [288.954 0.996 295.928 10.461] Andebo Hillary. /Matrix [1 0 0 1 0 0] /Type /Annot and LL.D.
