Wolfram Language for calculus?

How and what reference or codes in inputting for solving CALCULUS INTEGRATION PROBLEMS. Like this some topics:

  • VOLUME SOLID REVOLUTION,

  • WORK & PRESSURE,

  • AREA OF CURVE BOUNDED

  • VOLUME OF SOLID - CROSS SECTION

I wanted to learn on how to interpret it ( entering it to wolfram mathematica ) and let wolfram show its answer and 2D/3D graph..

Glad for quick help!

If you are using Wolfram|Alpha, please see this documentation. It shows examples of how to use Wolfram|Alpha for calculus:

To use Mathematica, you first need to learn a bit about how to program in the Wolfram Language:

Mathematica provides a number of functions for doing calculus:

You typically can visualize the results using the functions called Plot or Plot3D.

There bout 1000 and growing free-code examples on calculus at the Wolfram Demonstrations.
