my tnspire give me a wrong solution
Hi guys!
I have a this problem: my nspire give me the right result about a function (I know that because I've read it on my text)…but when I ask at my nspire to replace a value in this function, I've a wrong solution…why?
How can I add images from my desktop for a better comprehension?
Define piastre1()=
Prgm
:Define w(t)=∫(((1)/(t))*∫(t*∫(((carico(t))/(d)),t),t),t)+∫(((1)/(t))*∫(c1*t,t),t)+∫(((c2)/(t)),t)+c3
:Define α(t)=−(w(t),t)
:Disp "w(t) =",w(t)
:Disp "α(t) =",α(t)
:EndPrgmand then
carico(t):=((q*t)/(2))
piastre1()
0→c2
solve(α(a)=0,c1)I copy this result and define the constant
but if you set up t=a you have a wrong solution
α(t)
α(a)
