Maths Question on Quadratic Equations:​

Answer 1

Answer:

That is, the amino group at C-2 and hydroxyl group at C-3 are in cis ... Many monosaccharides, such as galactose (Gal), glucose (Glc),

Answer 2

Answer:

$from \: the \: quadratic \: equation \: {x}^{2} - px + q = 0 \\ tan \alpha + tan \beta = p \: \: \: \: \: \: tan \alpha \: tan \beta = q \\ tan( \alpha + \beta ) = \frac{tan \alpha + tan \beta }{1 - tan \alpha \: tan \beta } \\ tan( \alpha + \beta ) = \frac{p}{1 - q} \\ cos \: 2( \alpha + \beta ) = \frac{1 - tan {}^{2}( \alpha + \beta ) }{1 + tan {}^{2}( \alpha + \beta ) } \\ = \frac{(1 - q) {}^{2} - {p}^{2} }{(1 - q) {}^{2} + {p}^{2} }$
