In questions 1 and 2, you must state if you use standard limits, limit laws, continuity, l'Hopital's rule, sandwich theorem, or convergence tests for series. Question 1 (13 marks) Let f(x) = tan(r) log (sin(x)) (a) Use the definition of continuity to determine if the function f is continuous at r = 0. r page 19 - Page 2 of 19(b) Use the divergence test to determine if the series Ef n= 1 converges, or explain why the divergence test cannot be used
