Kalkulator Integral Tentu dan Tak Wajar

Kalkulator akan mencoba mengevaluasi integral tentu (yaitu dengan batas-batas), termasuk integral tak wajar, dengan menampilkan langkah-langkahnya.

Enter a function:

Integrate with respect to:

Enter a lower limit:

If you need `-oo`, type -inf.

Enter an upper limit:

If you need `oo`, type inf.

Please write without any differentials such as `dx`, `dy` etc.

If the calculator did not compute something or you have identified an error, or you have a suggestion/feedback, please contact us.

Solution

Your input: calculate $$$\int_{0}^{2}\left( \sqrt{y} \right)dy$$$

First, calculate the corresponding indefinite integral: $$$\int{\sqrt{y} d y}=\frac{2 y^{\frac{3}{2}}}{3}$$$ (for steps, see indefinite integral calculator)

According to the Fundamental Theorem of Calculus, $$$\int_a^b F(x) dx=f(b)-f(a)$$$, so just evaluate the integral at the endpoints, and that's the answer.

$$$\left(\frac{2 y^{\frac{3}{2}}}{3}\right)|_{\left(y=2\right)}=\frac{4 \sqrt{2}}{3}$$$

$$$\left(\frac{2 y^{\frac{3}{2}}}{3}\right)|_{\left(y=0\right)}=0$$$

$$$\int_{0}^{2}\left( \sqrt{y} \right)dy=\left(\frac{2 y^{\frac{3}{2}}}{3}\right)|_{\left(y=2\right)}-\left(\frac{2 y^{\frac{3}{2}}}{3}\right)|_{\left(y=0\right)}=\frac{4 \sqrt{2}}{3}$$$

Answer: $$$\int_{0}^{2}\left( \sqrt{y} \right)dy=\frac{4 \sqrt{2}}{3}\approx 1.88561808316413$$$
