So this may seem a bit odd at first - like why is it the the more of something there is, the less it costs to buy? But it actually makes a lot of sense when we break down the law of demand. The law of dem...

cos(4x) = cos(2(2x)) = 2(cos^2(2x)) - 1 = 2 (cos^2(x) - 1)^2 - 1 = 8(cos^4(x)) - 8(cos^2(x)) + 1

Diamond- Each carbon atom is bonded to four other carbon atoms with strong covalent bonds in a tetrahedral structure (with bond angles of 104.9 degrees). As all four valence electrons are used for bonding...

In DNA replication, first the hydrogen bonds between the nitrogenous bases are broken catalysed by the enzyme helicase, causing the DNA double helix to unwind and unzip, leaving the nitrogenous bases expo...

Firstly, increase the power outside the brackets by 1 and divide the whole thing by the new power. This gives 3/4(4x+1)^4/3Next, divide the whole thing by the derivative of the bracket. The deri...
