Task 1:
Note: You need to have your calculator in radians (RAD) mode for this task (since the angles are given in
radians -
i.e., π is featured).

a) A voltage waveform from a circuit under test, that you are displaying on an oscilloscope, looks as
follows:
0.00000
0.00004
0.00006

0.00006
O
0.0001
0.00012
You know that the signal takes the following form:
0.00014
OF
0.00016
0.00018
0.0002
0.00022
0.00024
000026
0.00028
v = V₂sin (2nft - 0)
Taking measurements from the oscilloscope display above, determine Vp, f, and Ø, and insert those
values into the above equation.
00003
0.00032
Now rearrange your new equation to make the time t, the subject of this formula and hence determine,
to within 3 decimal places, the first point in time when the voltage waveform has a magnitude of 5.25
volts.
0.0004
