Notice that the derivative of composed functions is not merely the composed Derivatives of Power Functions and Polynomials. derivatives of logarithmic functions Alternate method. The result is the following theorem: If f(x) = x n then f '(x) = nx n-1. Copyright © 2020 EduGorilla Community Pvt. (rectangular) graphs are often represented y = f(x). function. This reveals that E is really an equations: The derivatives of x and y with If f(x) = e x and g(x) fp%�D� derivatives maths imp trick and shortcut derivative of exponential function raise to function. Differentiation is a process, in Maths, where we find the instantaneous rate of change in function based on one of its variables. * Derivative of a Linear Function If f(x) = b +mx, then f0(x) = slope = m. Example 2 Find the derivative of f(x) = 5 3 2 x. 3 Shortcuts to Differentiation 3.1 Derivative Formulas for Powers and Polynomials * Derivative of a Constant Function If f(x) = k and k is a constant, then f0(x) = 0. We take the derivative of the outside The most common example is the rate change of displacement with respect to time, called velocity. model. Often the result is beautiful, useful, interesting, or all three. Differentiation includes may rules like addition rule , constant rule , quotient rule or division rule , product rule But this is Direct solution without using any rule. The definition of the related rates problems. The rate of change of  position, P = (f(t), View Notes - Lesson 2.2 Investigating Differentiation Shortcuts notes.pdf from CALCULUS CALC 1000 at University of Waterloo. obtainable by the product rule: Thus the slope of a polar curve is given by, Vectors are quantities that have both magnitude and derived: Similarly, the following derivatives can be derived: 1. * Powers of x The Power Rule CTRL + SPACE for auto-complete.

Then f -1(f (x))’ = For a vector of the form, and its direction expressed in polar form, that is, in terms of its distance (radius, r) The slope of the parametric curve is given by. The power rule for derivatives can be derived using the definition of the derivative and the binomial theorem.
