Calculate the time period of the waveform y(t)=7cos(54πt+2π÷4).(a)

1.	Calculate the time period of the waveform y(t)=7cos(54πt+2π÷4).(a) .055 sec(b) .037 sec(c) .023 sec(d) .017 secI had been asked this question in an online quiz.The above asked question is from Energy Relations During Starting topic in chapter Starting of Electric Drives
Answer» CORRECT answer is (B) .037 sec The explanation is: The fundamental TIME PERIOD of the cosine wave is 2π. The time period of y(t) is 2π÷54π=.037 sec. The time period is INDEPENDENT of phase shifting and time shifting.
