The Rectangle Method for Finding Areas
• Read over Example on pg. 351 and draw a conclusion about the Area under of curve as it relates to the number of rectangular sub-intervals.

The Rectangle Method for Finding Areas
• Read over Example on pg. 351 and draw a conclusion about the Area under of curve as it relates to the number of rectangular sub-intervals.
• When we become more comfortable with integration we will use integrals to more accurately find the area under a curve.

Anti-differentiation (Integration)
• The opposite of derivatives (anti-derivatives)
• Ex: You are given a velocity function and you want to find out what the position function is for the particle. How would you determine s(t)?
