You can optionally add an advanced condition for success, including inequalities and ranges. Note: If you set a condition here, the checkboxes above will be ignored.

A student's response will be marked correct if and only if this advanced condition is satisfied. Email support@desmos.com for assistance. You can use the following variables:
  • s: Sine or Cosine
  • P: Period
  • h: Horizontal Shift
  • k: Vertical Shift
  • a: Amplitude
