Other than the fact that, integral of 1/(1+x^2) is arctan(x). As you want to integral x from -1 to 1 you should keep a > 1 and send it to 1 from above. the first one gives cos^2 = 1-sin^2, and so we have identities that can be used to simplify 1-x^2 as well as 1+x^2, by putting x = sin (t) or x = tan (t). Examples.

 Here are some examples illustrating how to ask for an integral using plain English

. Solve indefinite integrals step-by-step. Therefore, we can replace x + 2 with u and replace dx with du in our integral to get the following: ∫ 1 ( x + 2) 2 d x = ∫ 1 u 2 d u. Because x2 +1 > 0 then ∣∣x2 + 1∣∣ = x2 + 1. We are going to let u = x + 2. dx = dy cos(y)2. Solution. In mathematics, trigonometric substitution is the replacement of trigonometric functions for other expressions.Tech from Indian Institute of Technology, Kanpur. The Integral Calculator solves an indefinite integral of a function. He provides courses for Maths, Science, Social Science, Physics, Chemistry, Computer Science at Teachoo. Verified by Toppr. en. Practice your math skills and learn step by … integrate x^2 dx. we know (at least) two basic trig identities with squares in them: sin^2+cos^2=1, and 1+tan^2 = sec^2, (obtained by dividing the first one by cos^2). Now, we rewrite and evaluate the integral in terms of u using our two rules above.

Moreover, one may use the trigonometric identities to simplify certain integrals containing radical expressions. ∫ dx (x2 +1)2 ≡ ∫ dy cos(y)2( 1 cos(y)4) = ∫cos(y)2dy. Many people have pointed out that the integral you are looking for is equivalent to, $$\sum_{n}^{\infty} \frac{1}{n!} \int_{0}^{x}x^{n}\ln(x)^ndx$$ To avoid ambiguous queries, make sure to use parentheses where necessary.
