Answer:
1st Harmonic:

3rd Harmonic:

5th Harmonic:

7th Harmonic:

Explanation:
The general form to represent a complex sinusoidal waveform is given by

Where A is the amplitude in volts of the sinusoidal waveform
Where f is the frequency in cycles per second (Hz) of the sinusoidal waveform
Where
is the phase angle in radians of the sinusoidal waveform.
1st Harmonic:
We have A = 50, f = 1000 and φ = 0

3rd Harmonic:
We have A = 9, f = 3000 and φ = 0

5th Harmonic:
We have A = 6, f = 5000 and φ = 0

7th Harmonic:
We have A = 2, f = 7000 and φ = 0

Note: The even-numbered harmonics have 0 amplitude that is why they are not shown here.
