if statement in r

For all real numbers x and y Let x and y be any two real numbers and let P(x)and Q(y) be the corresponding trigonometric points on the unit circle. In the above figures we have taken x and y so that The coordinates of P(x) are (cosx, sin x) and that of Q(y) are (cos y, sin y) by the defini..
