(Section 1.11: Limits and Derivatives in Calculus) 1.11.2 PART B: TANGENT LINES and DERIVATIVESIn Section 1.10, we looked at four forms of difference quotients. Form 1 gave us the average rate of changeof a functionfon a fixedinterval a,b±²³´, where a<b. This is equal to the slope of the secant lineon a,b±²³´. Form 1: Fixed intervalfb()±fab±aa, bare constants The other forms dealt with variableintervals. Each form, together with the idea of
