Homework Set 7 Name: __Ryan Corley __ Section: __4 __ 1. The graph of function f(x) is given below. (a) What is the value of the derivative at the x=1 and x=6? syms x a=11*sin((7/10)*x-2.25)+14 a =11*sin(7/10*x-9/4)+14 b=diff (a,x) b = -3773/1000*cos(7/10*x-9/4) x=1 x = 1 -3773/1000*cos(7/10*x-9/4) ans = -0.0785 x=6 x = 6 -3773/1000*cos(7/10*x-9/4) ans = 1.3967 I could not figure out the equation for the graph so I created my own that replicated the original as closely as I could. Logically speaking though, if you take the derivative of the graph at 1 and 6 the answers will both be zero since there is no slope at those points. (b) Is the derivative positive, negative or neither for x <1, 1<x<6, x>6? x=7 x = 7 -3773/1000*cos(7/10*x-9/4) 1
