Question

What's the best way to find Angles using logarithms and vice-versa.

Ex: log cot 0.1690 and log sin (25degrees 22min)

log sin (25+22/60)
= log sin 22.3666666667
= sin 0.38053243281
= (-0.41960832236)

Is there a simpler way to do these?

I get confused with finding the angles using logarithms

Answer 1

nope. to take the log, ya gotta find the sine first.

Of course, if you have a decent calculator, that means you just have to

enter 22/60+22=
then press deg sin log

Answer 2

But how can you do the inverse? such as

Log cot B 0.1690 = what angle?

should find the cot first then the log?

Answer 3

your expression makes no sense.
If you mean

log cot B = 0.1690

then that means

cot B = 10^.1690 = 1.4757
B = cot^-1 1.4757 = .5955
