We will learn later what these higher order derivatives are used for. (y double prime) is the third derivative. B : T L Notation for the Derivative: Lagrange Leibniz Find the derivative using the Definition of the Derivative (limits). Is the first derivative of y with respect to x. (slope of the tangent line) of B : T at any given Tvalue. Example: f(x) = | x |ĥ To be differentiable, a function must be continuous and smooth.ĭerivatives will fail to exist at: corner cusp discontinuity vertical tangent Note: The converse is false: there are functions that are continuous but not differentiable. Extend each tangent line well beyond the point of tangency in each direction. The Derivative and Tangent Line Problem Homework Name Name 2.2 Tangent Lines and the Derivative Homework Date Period Problems 1-6 line to the graph of g(x) V2 - x at x -7 5 Jean Adams Flamingo Math, LLC. We provide you all the answer keys for all the 2 2 tangent lines and the derivative homework questions, as well as a wealth of extra study materials online. Theorem: If f is differentiable at a, then f is continuous at a. Problems 36, sketch tangent lines to the given functions at each of the labeled points. posted on JDOWNLOAD 2 2 TANGENT LINES AND THE DERIVATIVE HOMEWORK AND GET THE ANSWERS We’ve got you covered. It is differentiable on an open interval (a,b) if it is differentiable at every number in the interval. dy / dx should not be regarded as a ratio.Ģ The derivative is the slope of the original function.Ī function f is differentiable at a if f ′(a) exists. If we replace number a by a variable x, then the derivative can be interpreted as a function of x : Alternative notations for the derivative: D and d / dx are called differentiation operators. In Section 2.1 we considered the derivative at a fixed number a.
