In this lesson, we will learn how to use sigma notation with Riemann sums to find the area under a curve.
Q1:
Represent the area under the curve of the function ๐(๐ฅ)=๐ฅ+2๏จ on interval [0,2] in sigma notation using right Riemann sums with ๐ subintervals.
Q2:
Find the lower Riemann sum approximation for ๐(๐ฅ)=5โ๐ฅ๏จ on [1,2], given that ๐=4 subintervals.
Q3:
Compute the right Riemann sum for ๐(๐ฅ)=(2๐๐ฅ)cos on ๏0,12๏ , given that there are four subintervals of equal width.
