A population of organisms exists with a set range of alleles. In an organism, a random mutation can result in the formation of a new allele. Some mutated alleles can be beneficial to an organism, and incr...

Rearranging gives:4cos(x)-1 = 2sin(x)tan(x) Substituting in tan(x)=sin(x)/cos(x) gives:4cos(x)-1 = 2sin(x)(sin(x)/cos(x))2sin²(x)=4cos²(x)-4cos(x)Substituting in 2sin^2<...
