Now substituting the value ofcos(270∘+0∘)in equation (iii), we getcos(270∘)=0 Hence, the cosine of 270 degrees is 0.For tangent of 270 degrees:We are well aware of the identity thattanθ=sinθcosθ Thus, we can writetan270∘=sin270...
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. ...
