what is the value of Cos1.Cos2.Cos3.Cos4 . . . . . . . . . . . . . . . . . . . . Cos180 ?

the answer is 0 because cos 90 is zero…

0

Cos 1 Value

0 as cos 90 is 0

The value is zero. Because Cos90 is zero and anything you multiply to zero would be zero. Therefore
Cos1.Cos2.Cos3.Cos4 . . . . . . . . . . . . . . . . . . . . Cos180 = 0

cos1.cos2.cos3………..cos180=0
this is because of the fact that anything multiplied by zero is nothing but 0.
as cos90 is 0,cos1.cos2.cos3.cos4……cos180=0

= 0 [zero]
as in between the expression there is cos 90 too which is = 0

0.because there is cos 90(0) in the middle

cos (180) = 1 cos (180) is also equal to 1, as cos (x) = cos (x)
