Introduction to Basic Graphs of Sine and Cosine Functions

What is the initial step in graphing the sine function using a T-chart?

• Plotting points using degrees

• Using a calculator to find values

• Choosing values in radians

• Drawing the graph directly

What is the sine of pi/2?

• 0

• 1

• Square root of 2 over 2

• -1

What is the period of the sine function?

• Pi/2

• 2 Pi

• 3 Pi

• Pi

What is the range of the sine function?

• Between -1 and 1

• All real numbers

• Between -2 and 2

• Between 0 and 1

What type of symmetry does the sine function exhibit?

• Symmetry with respect to the origin

• No symmetry

• Symmetry with respect to the y-axis

• Symmetry with respect to the x-axis

What is the cosine of 0?

• 0

• 1

• -1

• Square root of 2 over 2

What is the period of the cosine function?

• Pi/2

• 3 Pi

• Pi

• 2 Pi

What is the range of the cosine function?

• All real numbers

• Between -1 and 1

• Between 0 and 1

• Between -2 and 2

What type of symmetry does the cosine function exhibit?

• No symmetry

• Symmetry with respect to the x-axis

• Symmetry with respect to the y-axis

• Symmetry with respect to the origin

Why are both sine and cosine graphs referred to as sine waves?

• Because they have the same period

• Because they both have the same range

• Because cosine is a shifted version of sine

• Because they both start at zero
