6. Now you try ...
The pedals on a bicycle have a maximum height of 30 cm
above the ground and a minimum distance of 8 cm above the
ground. Jeng pedals at a rate of 20 cycles per minute.
a) What is the period, in seconds for this function?
b) At t = 0, Jeng's right foot is closest to the ground.
i) Write 2 equations that represent the height of her right foot above the
ground; 1 sine; 1 cosine.
ii) For how long per cycle is Jeng's right foot 20 cm, or higher, above the
ground?
