The value of $\bf cos 1^{0}\; cos2^{0}\; cos 3^{0} \;....cos 179^{0}$

$\huge\bold{Answer}$

$\sf\color{red}Cos 10 ×\: cos 20 ×\: cos 30 × ×\: cos \:17 90$

$\sf\color{blue}= cos 10 × \:cos 20 × cos 30\: × × cos\: 9 00 × ×\: cos 1790$

$\sf\color{red}= cos 10 × \:cos 20 ×\: cos 30\: × ×\: 0 × × \:cos 1790$

$\sf\color{purple}=\: 0$

Thankyou :)
