Question

prove that cos 1 into cos 2 into cos 3 and so on cos 90 is equal to zero​

Answer 1

since cos 90= 0

so, the whole equation becomes 0 because when we multiply any number with 0 it becomes 0

Answer 2

cos 1 into cos 2 into cos 3 and so on cos 90

cos 90 is 0

we know multiply by 0 is 0

hence proved
