We are pleased to announce the release of version 1.4 with one new functionality: Integration. You can compute the Integral of any equation with one, two or three unknowns. The unknowns are x, y, z. In this post we will compute the Integral of equation
x * y * z dxdydzMain Screen
We added a new button in the Main Screen, Integrals. You tap on it to enter the Integrals page.
Enter the Equation and Integral limits
There is nothing new in typing the equation. Like you do in the case of solving Algebraic equations or Plotting functions, you start writing the equation by using the different buttons in keyboard. When you type an unknown (x, y or z), a new section appears below the equation for entering the limits of that unknown. We arbritarily chose the limits for x to be [1,2], for y to be [7,8] and for z to be [5,6].
Integration
Once you have entered a valid equation, and the limits for each unknown, you tap on the Integrate button at the bottom of the page to compute the integral. If you have forgotten to enter the limits of an unknown, you will see an error message.
After a few seconds, the result is printed on the page. In this case, the Integration of this equations for these limits is 61,875. You can increase the accuracty of the result by going to the Settings page and increasing the number of digits to 6.
