 PARI/gp Xorter Fellow Posts: 66 Threads: 23 Joined: Aug 2016 04/17/2017, 09:48 AM Hi, again! I need your help in PARI/gp. I would like to substitute a value into x of sin(x): Code:`subst(sin(x),x,1)`But it returns with error. Why? Please, help me.

But why not simply do Code:`sin(1)` ? Oh, it was simplier than I thought. Thank you, my friend! Well, because I have found a new type of integration and derivation. These are iterated! And I needed substitution in a function in my gp. Really amazing. I am going to share my results on this forum as soon as possibly. (May be the key to determine what between addition and multiplication is.) Just wait a few days, please.

These methods are the generalizations of the integration and derivation... Xorter Unizo « Next Oldest | Next Newest »
