Question 1174867
.


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.
