# How do you find the exact value of arcsin [sin{(7pi)/6}]?

Jun 14, 2016

$\frac{7 \pi}{6}$

#### Explanation:

arcsin and sin are opposite (=inverse) functions, just like square and square root.

arcsin says: "give me the angle that belongs to a certain sine"

sin says: "give me the sine of a certain angle"

Together:
"Give me the angle that belongs to the sine of that same angle"
