The Power with Negative Exponent The Root of Odd Degree n From Negative number a The Properties of Powers with the Rational Exponents Permutations Arrangements Combinations and their Properties. To get tan^2(x)sec^3(x), use parentheses: tan^2(x)sec^3(x) Similarly tanxsec^3x will be parsed as tan(xsec^3(x)). http://colvertgroup.com/error-function/integral-error-function.php

You can access the Site Map Page from the Misc Links Menu or from the link at the bottom of every page. Most of the classes have practice problems with solutions available on the practice problems pages. Trapezoid Rule For this rule we will do the same set up as for the Midpoint Rule.  We will break up the interval  into n subintervals of width, Then on Error = |Approximation - Exact integral| Q Doesn't this raise a "Catch 22" situation? try this

So, from these graphs it’s clear that the largest value of both of these are at .  So,                            We rounded to make the computations simpler. Simpson's Rule If $n$ is even, and, as before, $x_k = a + kΔx = a + k (b - a)/n,$ then $\int_{a}^{b}\ f(x)\ dx \approx \frac{b - a}{3n} [f(x_0) + Paul's Online Math Notes Home Content Chapter/Section Downloads Misc Links Site Help Contact Me Close the Menu Cheat Sheets & Tables Algebra, Trigonometry and Calculus cheat sheets and a variety of 1. But if we knew the exact answer, then we would hardly need to find a numerical approximation in the first place! 2. Show steps SolutionYour input: approximate integral $$\int_{0}^{1}\sqrt{\sin^{3}{\left (x \right )} + 1}\ dx$$$ using $$n=5$$$rectangles.Trapezoidal rule states that $$\int_{a}^{b}f(x)dx\approx\frac{\Delta{x}}{2}\left(f(x_0)+2f(x_1)+2f(x_2)+...+2f(x_{n-1})+f(x_n)\right)$$$, where $$\Delta{x}=\frac{b-a}{n}$$$.We have that $$a=0$$$, $$b=1$$$, $$n=5$$$.Therefore, $$\Delta{x}=\frac{1-0}{5}=\frac{1}{5}$$$.Divide interval $$\left[0,1\right]$$$ into
