Описание: We will compute the exact value of sin(18 degrees), i.e. sin(pi/10), with this 18-72-90 special right triangle. We will also see the golden ratio during the computation when we use the quadratic formula! This is a classic geometry and trigonometry problem. If you like math, then you will enjoy it!
