Lim x->+inf xsin(1/x) | Physics Forums - The Fusion of Science and Community
Then differentiate both the numerator and the denomenator and then apply the limit thus f(x) = xsin(1/x) convert to f(x)/g(x) form i.e. f(x)/g(x) = sin(1/x)/1/x which is now in the form of 0/0 ,then according to La'Hospital rule f(x)/g(x) = f'(x)/g'(x) th...
