Waiting for answer How do you use the half angle identity to find cos 105?
Half Angle Formula ##cos(\theta/2)=pm sqrt{{1+cos theta}/2}## First, since ##105^circ## is the 2nd quadrant, cosine is negative, so by the half angle formula above, ##cos(105^circ)=cos({210^circ}/2)=sqrt{{1+cos(210^circ)}/2}## by ##cos(210^circ)=sqrt{3}/2##, ##=sqrt{{1sqrt{3}/2}/2}=sqrt{{...

Waiting for answer How does genetic drift differ from natural selection?
Both natural selection and are mechanisms for evolution (they both change allele frequencies over time). The key distinction is that in genetic drift allele frequencies change by chance, whereas in natural selection allele frequencies change by differential reproductive success. If the frequencies...
