Unformatted text preview: requency, f, is how often something occurs; a light that flashes 300 times per minute would flash 5 times per second or the light flashes with a frequency of 5 Hertz (Hz). Period, T, is the amount of time it takes for something to occur; so the light that flashes 5 times per second would flash once every 1 of a second or with a period of 1 seconds. 5 5 exercise: Pulsars are distant stars that appear to be brighter at short, regular intervals. At the beginning of this century, a pulsar was measured to pulse with a period of 2 seconds. After 10 years, its period had decreased to 1.9 seconds. It is assumed to decrease is linear. a) Write the function that describes the pulsar's period, T, as a function of t, the number of years from the beginning of this century. b) Use the period function to determine when the period becomes 0. c) Graph this pulsar's period function y = T(t) . y 0 t Unit 6: Day 5 notes - Reciprocal Functions (Part 2) Page 2 of 2 d) Write the function that describes the pulsar's frequency, f, as a function of t, the number of years from the beginning of this century. e) Use the frequency function to determine the pulsar's frequency at the beginning of the century. f) What is the frequency when the period becomes 0. g) Graph this pulsar's frequency function y = f(t) . Draw the period function's graph to help you draw the frequency graph. y 0 t...
