I used to think I wish I could go back and do it all over again. But, one look at that and you can keep it. Sorry. Good luck. I made it and you will too. Thanks God for scientific calculators. You've got one up on me.

Get an old trig book that publishes all these values. You will have to interpolate to get best results. This is superior to using a calculator which gives you the answer but not the basic theory behind logs.

Just type them into a scientific calculator. No other way short of a slide rule.
