ASSIGNMENT 14 - TAYLOR SERIES This week, we’ll work out some Taylor Series expansions of popular functions \(f(x) = \frac{1}{(1-x)}\) \(f(x) = e^x\) \(f(x) = ln(1 + x)\) \(f(x) = x^{\frac{1}{2}}\) For each function, only consider its valid ranges as indicated in the notes when you are computing the Taylor Series expansion. Please submit your...

Excersise 4.2 #9 A 24ft. ladder is leaning against a house while the base is pulled away at a constant rate of ft/s. At what rate is the top of the ladder sliding down the side of the house when the base is: First the equation needs to be derived with respect to time: \[ x^2 + y^2 = 24^2\\ 2x \frac{dx}{dt} + 2y \frac{dy}{dt} = 0\] \[-\frac{x}{y}...

1. Use integration by substitution to solve the integral below. \[\int 4e^{-7x} dx\] a. Sub in U for -7x \(u = -7x\) \(du = -7dx\) \(dx = \frac{du}{-7}\) b. Re-write as: \[\int 4e^{u}*-\frac{du}{7}\] c. Pull out dx \[ -\frac{4}{7} \int 4e^{u}*du\] d. Lastly integrate remaining problem and replace u \[\frac{-4}{7}e^{u}+C \rightarrow \frac{-4...
