how in the world do I find the asymptope of (e^x)/(1+e^x) i have no idea other than lim x->oo will come out with the verticle and lim x->o+ will comeout with the horizontal. ultimately i got y=1 and x=0 but is that correct?

Ok, I appologise if this question is obvious, but I'm still a high school student. We all know that anything times 0 = 0.
We also know that to find out if two lines are perpendicular to one another their gradients multiply together to make -1. A horizontal line and a vertical one are perpendicular to one another. Their gradients are 0 and infinite. Therefore 0 x ∞ = -1 which contradicts the earlier rule. Is it that the "perpendicular lines gradients product is -1" rule is insufficient to accomodate this exception? Or is there some other explanation?

Q) A teenager is mugged for his expensive, size 9, trainers by a white man. A white suspect from the same city is arrested wearing a pair of similar trainers.

There were 200 pairs of these size 9 trainers sold in the city. There are approximately 200,000 white males in the city.

a) Express the posterior odds of the suspect being guilty in terms of the prior odds.

b) If the prior odds are taken to be 1/200,000, what are the posterior odds of guilt?

c) What is the posterior probability of guilt?

I do the problem: limit 2 over 1 3x^-2. When I anti differentiate I get 3(x^-1)/-1 which means -3x^-1. I substitute the limits into the problem and get: -3 times 2^-1 which equals 6. And: -3 times 1^-1 which equals 3. The difference is 3 which is my answer, but the book says that the answer is 1.5
