We started class with a POD, which involved exponent properties. The class was interrupted by the clear the halls drill, but afterwards we took the concept quiz. We then moved on to a homework check, which concerned mostly the same things we've been working on: finding the area of trapezoids, estimating instantaneous rate of change, counting boxes ect. Then we took notes on the Trapezoidal Rule, which is an equation that lets you quickly add up all the components of multiple trapezoids to estimate the area under a curve. We finished class up by getting a new calculator program that does the traprule equation for you. The Homework for next class (1.4) requires this program, so make sure to talk to Ms. Sommariva if you don't have it.
TO USE THE PROGRAM: Hit the PRGM button on your calculator. Find the TRAPRULE option and hit enter, and then enter again. A= the lower bound, B= the upper bound and n= the number of trapezoids.
