Question

can i get the value of cos (1740)​

Answer 1

Answer:

Step-by-step explanation:

cos [1740] = cos [ 360 +360+360+360 +300]

                 = cos [4x360 +300]

                =cos [300]

                = cos [360 -60 ]

               = cos [-60]

               = cos 60

               =1/2

note

cos [360 +A] = cosA

cos[360-A] = cos[-A] = cos A
