 # Parameters:
-- `frequency`: [Hz] Frequency of sine wave
-- `amplitude`: Amplitude of sine wave
-- `phase`: [rad] Phase of sine wave
+- `frequency`: [Hz] Frequency of cosine wave
+- `amplitude`: Amplitude of cosine wave
+- `phase`: [rad] Phase of cosine wave
 - `offset`: Offset of output signal
 - `start_time`: [s] Output `y = offset` for `t < start_time`
 - `smooth`:  If `true`, returns a smooth wave. Defaults to `false`
