<span>Definition: The number of square units it takes to exactly fill a sector of a circle.
Do you want the exact equation? arc length is </span>Area= rl/2 and arc length is the same as sector area
Step-by-step explanation:
F(2)=3(2)²-7
=5

When you are asked what is the sin of π/6, or 30 degrees, you would look at the special triangle (30-60-90) to see that sin, or opposite over hypotenuse, of π/6 is 1/2. Arcsin, or csc, will present you with the ratio, 1/2, and ask for the angle. It's essentially working the question backwards.
