Is it (1/t)^2?

The units will cancel, (time)^2/(time)^2=1 Thanks for the help,

t^2 has (time)^2 and k has to have (1/(time)^2) ?

No, it is not going to cancel, but if I have k 1/time in (half hours), it does cancel? By the way, I am not a physics major, so bare with me please.

Is the dimension of k is (1/time(t)), in this case we have t in hours?

Any hints?

When I compute phi(2), it gives me 0.39 which is a real number.

Is't k just a constant?

Can you elaborate more please?

Thanks for the reply, I computed the second derivative with respect to t, I got phi^2(t)= 2*k*exp(-k*t^2)-4*k^2*t^2*exp(-k*t^2) Since we know that an inflection point occurs at t = 2, I solved for phi^2(2) = 0, which gives me k=0,1/8. so we choose k>0. Is my answer correct?

Homework Statement A two dimensional crystal process is modeled by an Avrami equation phi(t)= 1-exp(-k*t^2), where k>0. Experimental observation suggests that the inflection point of phi occurs at t=2 hours. Find the dimension and numerical value of k. Homework Equations I know how to...

Hello there, Is real analysis really important in the process of learning statistics? The reason is, I suck at real analysis(actually, I failed it) and do really good at stats(I am in my third yr. at uni.). Should I continue studying stats or switch to another major? I am looking...
