In ONE short paragraph, write a brief introduction to 'meiosis'?

Meiosis is a cell division. Its purpose is to produce
sperm and egg cells, which are reproductive cells. What it does is to cut the number of
reproductive cells in half. As we know, body cells have 46 chromosomes in the nucleus.
Therefore, meiosis is what splits the 46 into 23 chromosomes for each homologous
(similar) pair. The importance of this process is that it constitutes the making of the
biggest element for human characteristics.

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) ...
