You can use your graphing calculator (I used the online graphing calculator atHRW) to zoom in to where the lines meet. Note that in this example, the area is bounded by three functions, so you’ll need to perform more than one integration to find the solution. You can see a simple ex...
However, if the coefficient matrices are large or if the calculatory operations are performed with a small number of digits the round-off error may prevail. In this paper we investigate, by examples, the circumstances under which results are decisively affected by round-off error. The numerical...

Double Integral {eq}\int_{a}^{b}{\int_{c}^{d}{f\left( x,y \right)}}dxdy {/eq} can be solved by integrating {eq}f\left( x,y \right) {/eq} firstly with concerning to {eq}x {/eq} and then integrating with respect to {eq}y {/eq} and then substitute ...
What makes this an improper integral is its upper bound at infinity, but how does one deal with that? What makes infinity tricky to work with is that it is not a value one can just point at likeaorb; one can only approach it with a limit. Thus, instead of saying an improper integra...
Use a calculator to evaluate the integral from 2.1 to 5.9 of (e^x + cos(x))/(3x) dx. Evaluate the iterated integral: integral_{1}^{6} integral_{0}^{2} integral_{0}^{z} 2 z e^ {-z^2} dy dx dz. Evaluate the integral \int 36 e^...
