11.Is cos60 is greater or cos600? Justify youranswer |
|
Answer» 1. CosФ = adjacent side / hypotenuse in a right angle triangle = a/b. When angleФ = 0, a = b and asФ increases 'a' remains same and b,the hypotenuse increases. So cosФ decreases continuously asФ increasestillФ = 90 deg. 2. The graph of cosФ shows the wave like property of Cos and it decreases betweenФ = 0 toФ = 180 deg. So COS 6 is greater than COS 60. Cos6 has greater value than cos60. Because value of cos decrease from 1 to 0 in interval 0 to 90. |
