The solutions of f''(x) = 0 are the x-coordinates of possible inflection points on the curve y = f(x), where f'' denotes the second derivative of f. The second derivative of f(x) = esinx is:
f'' (x) = esinxcos2x - esinxsinx
Find all x in [0,2π] of possible inflection points.
Uhhhmmmmm...
also: our hint for this question is:
"keep in mind that the function g(t) = et is never zero for any real number t"
what is going on here?
Thanks in Advance:!)
