What are the three laws of logarithms?

There are many laws of logarithms, I do not know which
three you are referring you.


Here are a few laws that are
commonly used:


log(a*b) = log a + log b, used while
multiplying numbers


log(a/b) = log a - log b, used while
dividing numbers


log(a^n) = n*log a, used to find the power
of a number


log(a) b = [log(c) b] / [log(c) a], used to
change the base of the log from a to c


log(b) a = 1/ log(a)
b


log(a) a = 1

Calculate tan(x-y), if sin x=1/2 and sin y=1/3. 0

We'll write the formula of the tangent of difference of 2 angles. tan (x-y) = (tan x - tan y)/(1 + tan x*tan y) ...
