Hi everyone ! I'm a student, Can anybody tell me where to download a free version of mathcad 15.0 ?
There is no free version of MC 15. Programmers want to be paid for their work. But PTC sells a cheaper student license for educational purposes only.
Then there is a (of course free) 30-day trial version which you can download from PTCs website, but naturally it will stop working after the trial period.
Maybe your school/university offers even more discounted or even free edu licenses (then they pay for you) for its students, you'll have to check with your edu organisation.
You can download trial version of latest Mathcad 15 M045 service release here: Thank You for Your Interest in PTC Mathcad 15 | PTC
