Every straight line can be written in the form y=mx+c.(If they seem completely unfamiliar with concept):M is known as the gradient of the line, which says how steep the line is. The bigge...

By the sine rule, sin^-1(5/13)=22.6 degrees.Equally, by the cos^-1(12/13)=tan¹(5/12)=22.6 degrees.

First of all, replace sinxcosx with 1/2 sin2x. Then you should let U=1/2 Sin2x and replace that in the formula. If y=arctan(U), then U=tany. work out dU/dy which is Sec²y. Using the trigonometr...

At prophase I of meiosis, after the homologous pair of chromosomes pair up in the process called synapsis, the non-sister chromatids overlap, forming an X-shape. They then exchange their alleles at the po...

Ohms law establishes a relationship between resistance, voltage and current, saying that V/I = R.
