In this paper, we investigate the one-variable equation, sinx+cosx+tanx+cotx+secx+cscx=n, where n is an integer. We prove that if n lies between(inclusively) -1 and 6; then the above equation has no real number solutions. While if n is greater than or equal to 7; or less than ...
The trigonometric functions may be related to as functions of the x and y values of points on the unit circle where the angle is made by the radius and the positive x-axis. In particular,y=sinθandx=cosθwill be found on the unit circle. ...
