Sketch the appropriate curves. A calculator may be used. The intensity I of an alarm (in dBdecibel)

Question:

Sketch the appropriate curves. A calculator may be used. The intensity I of an alarm (in dB—decibel) signal is given by I = 40 + 50 sin t − 20 cos 2t, where t is measured in seconds. Display two cycles of I as a function of t on a calculator.
