+ Use the calculator at http://www.astro.ucla.edu/~wright/CosmoCalc.html to compute for at least two sets of cosmological parameters of your choice the following quantities at redshift z=0.5, 1, 1.5, 2, 5, 10: age of the universe in Gyrs; angular size distance in Gpc; luminosity distance in Gpc; angular size in arcseconds of a galaxy of 5kpc in intrinsic size. Plot these quantities as a function of redshift.
