Such calculations are routine, and in the Internet, there are TENS of web-sites with free of charge solvers
to do such routine calcs.
Therefore, a person who really wants to develop his (or her) skills, must do such work on his (or her) own, using
such calculators.
To come to the forum with such questions is the same as to ask here, how many is 2+2.
