Integration helps us to determine the original function of a derivative if provided one. If $\frac {d (F (x))} {dx}=f (x)$, then $\int f (x)dx=F (x)+C$ . This is known as indefinite integrals. $\int f (x)dx$ will represent the complete class of integral. What are some uses for …

Enter the function you want to integrate into the Integral Calculator. Skip the f (x)= part and the differential dx! The Integral Calculator will show you a graphical version of your input while you type. Make sure that it shows exactly what you want. Use parentheses, if necessary, e.g. a/ (b+c).

=\int_{0}^{\frac{\pi}{2}}f(\cos x)dx=\int_{0}^{\frac{\pi}{2}}f(\sin x)dx【结论一】 所以有 \int_{0}^{\pi}f(\sin x)dx=\int_{0}^{\frac{\pi}{2}}f(\sin x)dx+\int_{0}^{\frac{\pi}{2}}f(\sin x)dx

对于 cos^m x sin^n x 形式的函数，如果 m, n 都是偶数（没有一个是奇数），通常像上面那样使用倍角公式进行降幂。如果， m 或者 n 是一个奇数，那么，提取成

The integral of cos x dx is sin x. Mathematically, this is written as ∫ cos x dx = sin x + C, where, C is the integration constant. Here, '∫' is a symbol of integration and it is known as the "integral" cos x is the integrand; dx means the integration is with …
