Value of Sin 30° Cos 60°=
Answers!
We know from the Chapter Trigonometry.
There are standard value of Angles in the Table which you must have seen.
We know Sin(30°)= (1/2)
And Cos(60°)=(1/2).
As you can see both values are same so it concludes that Sine & Cosine are COmplementary Functions that's why there is COsine there.
SO,your requred answer is (1/2)×(1/2)
Hence, The answer of Question i.e, Sin(30°)Cos((60°)=(1/4).
