CS 173 Chapter 7.1-7.3: Functions

a.A sinewave has a period (duration of one cycle) of 645 μs. What is the corresponding frequency of this sinewave, in kHz, expressed to 3 significant figures? (See Study Note 7.1 in the ‘Using Numbers (maths)’ booklet.)

A (i) If the frequency of the sinewave is now reduced by a factor of 3.5, what will be the new period value? Express your answer in ms, to 3 significant figures.

Note: In the second part of this question, to avoid rounding errors in your calculations, use the full frequency value from the first part, not the rounded value to 3 significant figures.
