okay its a calculus project.. and I'm stuck.

I am suppose to find the point of inflection from an equation I got which is:

P= 193.93/[1+13.69e^(-.3954t)]

I think by taking the 2nd derivative and setting it equal to 0 will give the point of inflection... but it is not working out.

could someone please help me?

second derivative and setting it equal to 0 is right .. are you sure that you're getting the second deriv correctly? i got t = 6.61777... btw
