plz answer!!!

Hi Jahnavi!
 
Here is the answer to your query.
 
cos 1° ×.cos 2° × cos 3°....... × cos 179°
= cos 1° ×.cos 2° × cos 3°... × cos 89° × cos 90° × cos 91° × ... × cos 179°
= cos 1° ×.cos 2° × cos 3°... × cos 89° × 0 × cos 91° × ... × cos 179° [cos 90° = 0]
= 0
 
Hope! This will help you.
Cheers!!!

 0, bcoz

cos1*cos179

= cos1*sin1=1 and so on.....

only cos90 and cos 180 will be left at last,

cos90*cos180

= cos90*cos(180-90)

=cos90*cos90=0*0=0

The value of this expression is 0
