What does "cosecant" represent in trigonometry?

• The ratio of the length of the side opposite to an acute angle to the length of the hypotenuse.

• The length of the hypotenuse divided by the length of the side opposite the angle.

• The length of the side adjacent to an acute angle divided by the length of the hypotenuse.

• The ratio of the length of the hypotenuse to the length of the side opposite the angle.

Answer explanation

The cosecant in trigonometry represents the length of the hypotenuse divided by the length of the side opposite the angle.

F(x) = Asin[B(x-C)] + D is the standard form. A is the Amplitude B helps you find the period, B=2pi/period C is the phase shift D is the vertical shift Then f(x) = 2Sin(3x + 1) + 4

• 4

• C, phase shift

• 2

• D, vertical shift

• 1

• A, amplitude

• 3

• B, helps calculate period
