Expert II Introductory Sinusoidal Functions 30-2

Question 1

Be able to draw the graph y = sin(x) from memory

Answer 1

Recognize the period is 2π or 360° and that you start at the origin, move up to 1, back through the x - axis, down to -1 and back to the x-axis. Then use that pattern core to complete infinite cycles to the left and right.

Question 2

Know how to shift the sinusoidal graph up by a set amount of units.

Question 3

Know how to shift the sinusoidal graph down by a set amount of units.

Question 4

Know how to shift the sinusoidal graph left by a certain amount of units.

Question 5

Know how to shift the sinusoidal graph right by a certain amount of units.

Question 6

Know how to calculate the range of a sinusoidal graph.

Question 7

Know how to amplify the sinusoidal graph by a certain multiplier.
