Question

Find the limit:

lim x-->0 sin5x/sin4x

is it 5/4?

Answer 1

0/0 indeterminate you'll have to somehow rewrite it unless you are in calculus 2

Answer 2

it will be 5/4 though

Answer 3

so whatever you did was correct

Answer 4

cool. thank you!

Answer 5

U can use l'Hopital's rule right?

Answer 6

since it is in 0/0 form u can use l hospitals rule.

i.e u can differentiate the numerator and denominator seperately.

so u will get 5 ( cos 5x)/4 ( cos 4x)

now u can substitute 0

then u will get the answer as 5/4

Answer 7

Yes you can use l'hopitals as long as it's in 0/0 form

Answer 8

or infinity over infinity -infinity/infinity
