(n.d.). Lisas situation with spatial imagination is bad (and not only), therefore, having encountered the topic Geometric applications of a certain integral in her university, Lisa specifically booted up, in the sense, she was sad because she didnt even cry. Now suppose that the function has a discontinuity at x = c and is continuous between $(a, c] \cup (c, b]$. Step no. Step 4: Integrate the improper integral with respect to x. There are many ways to calculate improper integrals. Additionally, you can load samples to test the calculator. The trick is finding a comparison series that is either less than the original series and diverging, or greater than the original series and converging. If the function is specified for the range $ (-\infty,b] $, then the integral is as follows: \[\int\limits_{ \infty }^b f\left( x \right)dx = \lim\limits_{n \to \infty } \int\limits_n^b {f\left( x \right)dx} \]. Improper integral is used to measure the function value whether it exists or not at the defined limits. C is constant. Step \(\:\int _1^{\infty \:\:}\frac{1}{x^2}dx=\lim _{a\to \infty }\left[-\frac{1}{a}-\left(-\frac{1}{1}\right)\right]\), \(\:\int _1^{\infty \:\:}\frac{1}{x^2}dx=\lim _{a\to \infty }\left[-\frac{1}{a}+1\right]\), \(\:\int _1^{\infty \:\:}\frac{1}{x^2}dx=\left[-\frac{1}{\infty }+1\right]\), \(\:\int _1^{\infty \:\:}\frac{1}{x^2}dx=-0+1\), \(\:\int _1^{\infty \:\:}\frac{1}{x^2}dx=1\), Use android or iOS app of our limit calculator on your mobile, $${ {\color{gray} }(cos(x)^3*sin(x) ) dx}$$.
