The product of sin 30 degrees and sin 60 degrees is the same as the product of
zysi [14]

Answer:

sin(30\°)*sin(60\°)=cos(60\°)*cos(30\°)

Step-by-step explanation:

we know that

sin(\alpha)=cos(\beta)

when

\alpha+\beta=90\° -------> complementary angles

so

sin(30\°)=cos(60\°)

sin(60\°)=cos(30\°)

Because

30\°+60\°=90\° -------> complementary angles

In this problem the product of

sin(30\°)*sin(60\°)

is equal to

cos(60\°)*cos(30\°)

therefore

sin(30\°)*sin(60\°)=cos(60\°)*cos(30\°)
