Let π» = { π§ β β βΆ |π§| < 1} and π: π» β β be defined byΒ
\(f(z)=\rm z-25z^3+\frac{z^5}{5!}-\frac{z^7}{7!}+\frac{z^9}{9!}-\frac{z^{11}}{11!}\)
Consider the following statements:
π: π has three zeros (counting multiplicity) in π».
π: π has one zero in π = { π§ β β βΆ \(\frac{1}{2}\)Β < |π§| < 1}.
ThenΒ
1

3
both π and π are TRUE
4
both π and π are FALSE
