Question

value of Cos 0 degree into cos 30 degree into cos 45 degree into Cos 60 degree into cos 90 degree is equal what and how? ​

Answer 1

It's equal to 0.

$\cos(0) \times \cos(30) \times \cos(45) \times \cos(60) \times \cos(90) \\ = 1 \times \frac{ \sqrt{3} }{2} \times \frac{1}{ \sqrt{2} } \times \frac{1}{2} \times 0 \\ =0$

Answer 2

given question

given questioncos(0)×cos(30)×cos(45)×cos(60)×cos(90)

we know

cos(0)=1

cos(30)=root3/2

cos(45)=1/root2

cos(60)=1/2

cos(90)=0

subistuting the values

=1×root3/2×1/root 2+×1/2×0

=root3/4root2×0

=0

since the answer is 0
