Question

Find the value of $cos{0}^{\circ }\times cos{1}^{\circ }\times cos{2}^{\circ }\times ......cos{90}^{\circ }?$

• A.
  1
• B. 0
• C. -1
• D. None of these

Answer 1

The correct option is B 0

$\Rightarrow cos{0}^{\circ }\times cos{1}^{\circ }\times cos{2}^{\circ }\times ....cos{90}^{\circ }\Rightarrow 0$
[$Cos{90}^{\circ }=0$]

Hence, Option (b) is correct.
