Integral Calculator

The integral calculator gives chance to count integrals of functions online free. This calculator allows test solutions to calculus exercises. It helps to gain experience by displaying the full working process of solving the problem and exercises. The every single and general integration techniques and even unique, important functions being provided.

How to use

The Integral Calculator provides definite and indefinite integrals. There is an opportunity to check the answers. It works writing the function to integrate. Click “Go!” to begin the integral calculation. The result will be shown further below. Just click the blue arrow and there appears a solved example.

Modify that expression as needed. This is great for checking the work, experimenting with different equations, or reminding how to work a particular problem. It is great for quick answers.

Someone was doing their homework in my calculus-based physics class and I watched them pull up an integral calculator to find the integral of xdx

To anyone in Calc that also procrastinated the 6.2 hw till tonight, there's an Indefinite Integral calculator from symbolab. You're welcome

me, plugging in all my homework questions into integral calculator dot com and copying down the answers: this is so much work why is this class so hard

One of the greatest trick to life is knowing how to solve differential and integral calculus with a calculator. That shit saved my life in the university.

Today I'm applying the Inverse Calculator Law. Whereby popping calc is an integral part of an exploit chain rather than the end result 😃

Pretty sure the online integral calculator has done more for me than half of my friends.

If a u have to wait more then a minute for your calculator to calculate the integral then its to hard of a problem, this sucks.

I plugged a really complicated integral into my calculator and it's said "busy" for the past five minutes I think I broke it #help

College: let's solve the integral of this trig function because we will need to for our future jobs.
Real job: 2+2..where's the calculator?

    xe^(1/x)-e^(1/x))/(x+x^2e^(1/x))

    taking so much time???

      This requires much time, because integration by parts should be applied 3 or 4 times.

    triple and double integral step by step solution would be nice too

      triple and doube integral are multiple applications of this integral. however, to check the answer, use double (triple) integra

    Here’s a problem correctly solved.

    ∫ ∂r / √[2GM(1/r−1/b)]
    = √[b/(2GM)] { √(rb−r²) + b arctan √(b/r−1) } + K

    You should get the indefinite integral calculator on this page to solve it well. The best way to begin is factor out some contstants and use the substitution as shown

    √[b/(2GM)] ∫ ∂r/√(b/r−1)

    u = √(b/r−1)
    ∂u/∂r = −½ b r⁻² / √(b/r−1)
    r = b/(u²+1)
    ∂r = −2b u/(u²+1)² ∂u

    −2b √[b/(2GM)] ∫ ∂u/(u²+1)²

    You can use an alternate substitution, u = d/r, but if you do you’ll obtain the answer in the more cumbersome form of complex natural logarithms, which you can transform into the form having the arctangent term through Euler’s theorem. But it’s best to get the better form the first time through.

    Integral of sqrt(19 − 18x − x2) took too much time; no steps

      Complete the square.
      Answer is 1/2 sqrt(-x^2 – 18 x + 19) (x + 9) + 50 asin((x + 9)/10) + C
