How do I change my keyboard layout back to English QWERTY on Kodachi Linux?

0 For some reason the letter I changes to a 5. J changes to 1 K changes to 2 L changes to 3 M changes to 0 N is normal O changes to 6 P changes to * Q is normal R is normal S is normal T is normal U changes to 4 V is normal W is normal X is normal Y is normal Z is normal I'm in the USA, American & use a US layout on my Dell Vostro 1520. What's the deal? How do I fix this? keyboard share | improve this question asked Jan 2 at 21:00 Kevin Gibbs ...

Why are logarithms of trigonometric functions useful?

6 0 $begingroup$ I have noticed that in many trigonometric tables the logarithm of the trigonometric values are given. Why this is given and not the actual values of the trigonometric functions? For example, instead of listing the value of $sin(43^circ)$, it is the value of $log(sin(43^circ))$ that is listed. The only reason I cam come up with is that in the use of the law of $sin$: $$ frac{sin(A)}{a} = frac{sin(B)}{b} $$ taking logarithms on both sides one gets $$ log(sin(A)) - log(a) = log(sin(B)) - log(b) $$ making it easier to use that specific formula. But this wouldn't work with the law of cosine. Are there other reasons to prefer logarithms of trigonometric functions over just the actual values of the trigonometric functions? trigonometry r...
