Pre-Calc Review

Front

Write an equation for the cosine function with amplitude 3, period 2pi, phase shift of pi, and vertical shift of 5.

Back

y = 3cos(x - pi) + 5

Front

Which is the correct set up to solve for x? sin 24 = x / 12, cos 24 = x / 12, tan 24 = x / 12

Back

tan 24 = x / 12

Front

What is the side across from the right angle called? Leg, Pythagoras, Hypotenuse, Altitude

Back

Hypotenuse

Front

What equation can be used to solve for x? Sin(40°)= x/40, Sin(40º)=x/19, Cos(40º)=x/19, Tan(40°)=19/x

Back

Sin(40º)=x/19

Front

If you are given the hypotenuse and an adjacent side, which trig function should you use? sine, cosine, tangent, cotangent

Back

cosine

Front

What is the amplitude of a sine function?

Back

The amplitude is the maximum distance from the midline of the wave to its peak or trough.

Front

Define the period of a trigonometric function.

Back

The period is the distance along the x-axis required for the function to complete one full cycle.

Front

What is the phase shift in a trigonometric function?

Back

The phase shift is the horizontal shift left or right for periodic functions.

Front

How do you find the sine of an angle in a right triangle?

Back

Sine = opposite side / hypotenuse.

Front

How do you find the cosine of an angle in a right triangle?

Back

Cosine = adjacent side / hypotenuse.
