Finding minima of function.
For what value of 'k' (in terms of $X_{i}$'s) following functions will attain their minimum value $\rightarrow$ $F_{1}(k)$ = $\sum_{i=0}^{n} \left  X_{i}  k \right $ $F_{2}(k)$ = $\sum_{i=0}^{n}\left ( X_{i}  k \right )^{2}$ If possible, please provide some valid proof for supporting your answer ?

(A) 5 (B)1 (C)4 (D) 0 Solution: f(x) = $2x^3  3x^2$ f'(x) = ... then what will be the answer 5 or 1, as closed intervals are given, so in case of local minimum also we should consider the extreme points, right?

Consider the function f(x)=sin(x) in the interval x=[π/4,7π/4]. The number and location(s) of the local minima of this function are (A) One, at π/2 (B) One, at 3π/2 (C) Two, at π/2 and 3π/2 (D) Two, at π/4 and 3π/2 Please explain how pie ... is points where slope is 0 for f(x) not the end points.End points is used for absolute minima/maxima ( as much as i have read in books that is).

Maxima and minima
Could we always say that in case of local minima or maxima we do not consider the extreme points we only check for critical points while in case of absolute maxima we check both at end points as well as at critical point...Please correct me if I am wrong.
