1itnaaa Genius in this site,..........and no repliezzzzz........[3][3][3]..............[9][9][9]........
1) Evaluate limx->infinity cosx/x or explain why it doesnt exist?
2) Evaluate lim t->4 (t-√3t+4)/t-4 or explain why it doesnt exist?
3) Evaluate lim x->13√ x-1/√x-1 or explain why it doesnt exist?
4) Let f(x)= sinx/x if x#0
f(x)= 1/2 if x=0
Discuss the continuity of f(x) and Sketch.........

33hey first one is zero...
-1/x≤cosx/x≤1/x ... (x>0)
apply sandwitch theoremm...
333rd .. doesnot exists.. as denominator.. becomes undefined for
LHL
1hey can u check once more ur answer....2nd.......????[7][7][7].......
1im getting 5/6.....may be some problem while my solving.....[2][2][2]..........
3i think first one doesnt exist
L is a no dat is defined but in the first ques cos∞=f(X) and g(x)=x which is also not defind so limit wont exist.
33hey...
as x becomes larger and larger... cos(x)/x tends to zero....
33what about...
lim x/x2 ....
x→∞
same hai balki isse bhi jaldi zero ho jaega...
1ya i got it now.....thanks sky.......but i forgot to rite thats all....[1][1][1]..
1first has to be zero...
num is finite but deno infinite..
so something like k/∞ =o
