About This Worksheet

This medium-level worksheet contains 14 problems designed for 11th Grade students practicing graphing trig functions. Medium worksheets introduce larger numbers and varied question formats to deepen understanding and build fluency.

Use radians, the unit circle and exact special-angle values.

  • Practice exact trigonometric values and identities with angle units and domains stated.
  • Check your result using the method in the example before moving to the next question.

How to Solve: Worked Example

Example Problem: For y = 3 sin(1x), give the amplitude and period, then sketch one period using five key points. Angles are radians.
Solution Steps:
  1. Amplitude is the absolute value of the coefficient.
  2. Period is 2π divided by the positive coefficient of x.
  3. Divide the period into four equal intervals; the sine values are 0, 1, 0, −1, 0.
Answer: Amplitude 3; period 2π/1. Key points: (0, 0), (π/2, 3), (π/1, 0), (3π/2, −3), (2π/1, 0).
Tip: Check your result using the method in the example before moving to the next question.
