**Area**Section 5.2**Overview:**Summation Formulas: Rectangular Area: Area under the curve:**Summation Formulas:**(back)**y = f(x)**Rectangular Area: Area of a Rectangle = base * height A = height x base A = height · ∆x ∆x A = y · ∆x A = f(x)· ∆x (back)**Area under the curve:**Approximating Area using Rectangles and Summations RAM : Rectangular Approximation Method LRAM MRAM RRAM Demo: Class Example (RAM): Unlimited / Infinite amount of Rectangles… (back)**Class Example:**Estimate the area under the curve from [0,2] for y = -x^2+5 using RRAM with five rectangles (back)**Infinite Number of Rectangles**Add more rectangles (back)
