zero will be the answer

Answer 2

Hey,

Here is your answer,

Step-by-step explanation:

= Cos 1° x cos 2° x cos 3° x cos 4° x ......x Cos 90° x ....... x cos 180°

= Cos 1° x cos 2° x cos 3° x cos 4° x ......x 0 x ....... x cos 180°

( Since the value of cos 90° is 0)

So,when we substitute the value of cos 90° , 0 is multiplied with the entire term to give 0

= 0

Hope it helps you!
