Solve for x. ln x^3 = 2 + ln x

lnx^3 = 2+lnx. To solve for
x.


=> 3lnx = 2+lnx, lnx^3 = 3lnx, as lna^m = m
lnx.


=> 3lnx- lnx =
2.


=> 2lnx =
2


=> (2lnx)/2 = 2/2 =
1.


=> lnx =
1.


=>  x = e =
2.718281828.


lnx^3 = 2+lnx. To solve for

2.


=> 2lnx =

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) ...
