Prerna Sharma, a B.Tech student, conducted an experiment using MATLAB to draw the waveforms of log(x) and log(x^2). She created code that defined x and y variables, took the log of x and x^2, plotted the results, and added a grid. The waveforms were successfully drawn.

(b) code for log (x^2)
>> x=0:0.001:20
>> y=log(x.^2)
>> plot(x,y)
>> grid()
RESULT: -
We have successfully drawthe waveformof log(x) and log (x^2).
