The following are all suggestions, not requirements, and you certainly shouldn't attempt to investigate all of these. You might investigate: • more quickly convergent methods, like the Gauss-Legendre algorithm, the Borwein algorithm, or others. approximations given by the continued fraction expansion for . digit extraction methods. • the decimal module, for obtaining more accuracy than floating point arithmetic allows. .arrow_forward1.

A parsec is a unit of astronomical distance, equal to about 3.26 light-years. One parsec corresponds to the distance at which the mean radius of the Earth's orbit subtends an angle of one second of arc. Since the numbers grow so large so quickly, it's often easier for astronomers to work with parsecs, and convert them back to light years, or even miles, when needed. Write a function to convert parsecs to light-years. (computer language: C)arrow_forwardarrow_back_iosSEE MORE QUESTIONSarrow_forward_ios
