Lim sin2h sin3h / h^2
h>0
how would you do this ?? i got 6 as the answer, just want to make sure it's right.
and i couldn't get this one (use theorem 2)
lim tanx/x
x>0
and also this one (use squeeze theorem to evaluate the limit)
lim (x1)sin Pi/x1
x>1

Reiny
the first one is correct.
Here is a simple way to check your limit answers if you have a calculator
pick a value very "close" to your approach value, in this case I would pick x = .001
evaluate using that value, (you are not yet dividing by zero, but close)
I got a value of 5.999985 which I would say is close to 6
for lim tanx / x as x >0
= lim (sinx/cosx)/x
= lim (sinx/x)*lim 1/cosx as x > 0
= 1*1 = 1
If you meant lim (x1)sinπ/(x1)
wouldn't the last one simply be sinπ or 0 ?

Suppose lim x>0 {g(x)g(0)} / x = 1. It follows necesarily that a. g is not defined at x=0 b. the limit of g(x) as x approaches equals 1 c.g is not continuous at x=0 d.g'(0) = 1 The answer is d, can someone please explain how?

I have a question relating to limits that I solved lim(x>0) (1cosx)/2x^2 I multiplied the numerator and denominator by (1+cosx) to get lim(x>0) (1cos^2x)/2x^2(1+cosx) = lim(x>0)sin^2x/2x^2(1+cosx) the lim(x>0) (sinx/x)^2 …

Show that limit as n approaches infinity of (1+x/n)^n=e^x for any x>0... Should i use the formula e= lim as x>0 (1+x)^(1/x) or e= lim as x>infinity (1+1/n)^n Am i able to substitute in x/n for x?
