Final answer:
The student is requesting help on finding a Taylor series for a complex function with center at z0=-π. The Taylor series in question is for the function 1/(z-i)² and does not relate to the statistical information provided about the TI-83, TI-83+, or TI-84+ calculators.
Step-by-step explanation:
The student is asking to find the Taylor series for the function 1/(z-i)² with the center at z0=-π. To find the radius of convergence for this Taylor series, we can use the fact that it will converge on the disk where the function is analytic, which is everywhere except at the singularity z=i. Therefore, the radius of convergence would be the distance from z0=-π to the singularity at z=i, which can be found using the distance formula in the complex plane. However, the provided information from the use of TI-83, TI-83+, or TI-84+ calculators seems to be about a different topic related to normal distributions and not directly relevant to the Taylor series question. The command invNorm(0.975,0,1) finds z0.025 in a statistical context, not in the context of determining the Taylor series or its radius of convergence.
