Question
In (0, π), f(x) = sinmx + cosecmx, attains -
Options
A.a maxima independent of m
B.a minimum value which is a function of m
C.a minimum value which is independent of m
D.the minimum value at the same point independent of m.
Solution
Using AM ≥ GM
sinmx + cosecmx ≥ 2
minimum value is 2 at x =
sinmx + cosecmx ≥ 2
minimum value is 2 at x =
