Back

Front

Describe the horizontal and vertical shifts of the function y = f(x).

Back

Horizontal shift: left π, Vertical shift: down 3

Front

What is the period of the function y=cos(3x - π) - 5?

Back

Front

State the Law of Sines.

Front

What is the equation of the graph if it is a cosine function shifted left by π/2 and up by 3?

Back

y = 2cos(θ + π/2) + 3

Front

How do you find the period of a trigonometric function?

Back

Front

What is the relationship between sine and cosine in a right triangle?

Back

@@ ext{sin}( heta) = rac{ ext{opposite}}{ ext{hypotenuse}}; ext{cos}( heta) = rac{ ext{adjacent}}{ ext{hypotenuse}}.

Front

What is the formula for the area of a triangle using sine?

Back

Front

What does a horizontal shift to the left by π mean for the function y = f(x)?

Back

The function is translated left by π units, changing the input to f(x + π).
