my VPA solve was working fine and then after running twice, I suddenly have an "Index exceeds number of array elements (1)"
This is what I am running, and its extremely simple. I dont know why it would stop working after functioning prior.
syms t
P(t)= 30/(3+7*exp((-.03*t)))
P(1960)
vpa(P(1960))

I'm confused, because the code you posted runs fine:
syms t
P(t)= 30/(3+7*exp((-.03*t)))
P(1960)
vpa(P(1960))
Is it possible that somewhere in between you defined P as a variable, and then tried to access?
P = 7;
vpa(P(1960))
