Step-by-step explanation:
[tex]sin \: 30 \degree \times sin \: 60 \degree \\ = \frac{1}{2} \times \frac{ \sqrt{3} }{2} \\ = \frac{ \sqrt{3} }{4} \\ \\ cos \: 30 \degree \times cos \: 60 \degree \\ = \frac{ \sqrt{3} }{2} \times \frac{1}{2} \\ = \frac{ \sqrt{3} }{4} \\ \\ thus \:\\ sin \: 30 \degree \times sin \: 60 \degree = cos \: 60 \degree \times cos \: 30 \degree \\ [/tex]
The product of sin 30° and sin 60° is same as the product of cos 60° and cos 30°.
Answer:
Cos 60 degrees and cos 30 degrees
