[sage-support] How to prevent simplifying

2013-02-27 Thread Princess Chidinma Anusionwu

I am trying to find the maximun of an exponential expression of the form: sage: t=var('t') sage: g(t) = e**(-t/10)-e^(-t/2) between 0 and say 50. My idea is to get the maximun to normalize the function to that maximum and obtain the algebraic. For that: sage: diff(g,t)==0,t) But sage

In theory, sage: 4/sqrt(18,hold=True) should work, but apparently we didn't implement that, nor a hold keyword with exponents (?). Burcin, can you think of a way to do this? On Wednesday, February 27, 2013 3:58:06 AM UTC-5, Princess Chidinma Anusionwu wrote: Hi I want sage to show
