Help with limits

[vital eagle]

-the first one u just plug 2 and u will get 0

-the second one u can do it by subtitution n x/2=t and use the defined limit: lim when t approaches 0 of sin(x)/x is 1

-the third limit u just multiply buy the conjugate of the numerator and simplify after with the 'x', u will get 1/4

-the fourth limit approaches what? 0 or n?

if it approaches 0 ,set that function = f(x)

u will calculate the limit of ln(f(x)) [u can do this because f() is continued , that value u will get will be the exponent of 'e', so te result will be e^[the value u will get after calculation ln(f(x))]

Ah thankyou @vital eagle much appreciated

i still dont understand the 2nd and 3rd

[golden bridge]

which part?

-the third one you will multiply the numerator and denominator both by sqrt(1+X) - 1 and calculate it, then u just replace 0 on ur variable 'x'
