[FEATURE REQUEST] Riemann Integration

[il798li]

What would you like to Propose?

We can use an algorithm that uses Riemann's Left/Right/Midpoint/Trapezoidal sums to approximate the value of definite integrals.

Issue details

Using a deltaX, this will specify the width of each sub-interval. From there, based on the type of Riemann sum, the height of the rectangle can be determined. We can simply add up the areas of all rectangles to estimate the value of a definite integral.

Hi, I'd like to work on this issue. Can you please assign it to me?

@shankagr7805 @VSENTHAMIZHAN I was thinking of working on the issue myself. I have some basic code down already: https://github.com/il798li/Java/blob/master/src/main/java/com/thealgorithms/maths/RiemannIntegration.java

@il798li Hey! I went through your code — it's super clean and well-structured,
Would you be open to me contributing by adding a few things like:
1)Unit tests for all methods.
2)Optional generalization: allowing user to set number of intervals directly (instead of just accuracy).
3)Some input validation or performance notes. Let me know if you'd like me to take a stab at any of these.

[il798li]

@VSENTHAMIZHAN sure! Do I need to authorize you anywhere for you to make these changes?
Apologies for my lack of knowledge, I'm fairly new in contributing to open-source projects.
