Answer:
The product of sin30 and sin60 is the same as the product of cos60 and cos30.
Explanation:
First of all, note that the following are correct:
cos60° = 0.5
sin60° = (√3)/2
cos30° = (√3)/2
sin30° = 0.5
sin30 × sin60 = 0.5 × (√3)/2 = 0.43301
Obviously, just by mere inspecrion,we see that
cos60 × cos30 = 0.5 × (√3)/2 = 0.43301
In conclusion, the product of sin30 and sin60 is the same as the product of cos60 and cos30.
