Describe the stages in DNA transcription and translation

First DNA helicase unwinds the strand of DNA. Then, DNA polymerase binds to the anti-sense strand of the DNA and adds RNA nucleotides in a sequence complementary to the strand of DNA. The DNA polymerase cata...

find dy/dx at t, where t=2, x=t^3+t and y=t^2+1

We know from simple fraction rules that dy/dx=(dy/dt)/(dx/dt). dy/dt=2t, dx/dt=3t^2+1. Therefore, dy/dx=2x2/12+1=4/13

A curve has equation x^2 + 2xy – 3y^2 + 16 = 0. Find the coordinates of the points on the curve where dy/dx =0

We would do this by differentiating everything individually so to differentiate x 2 we multiply the x 2 by the power which is 2 and then take the power down by 1 to make 2x. To differentiate 2xy we would use...
