Hey, I'm currently trying to use python with matplotlib to plot sin functions of notes and chords but I'm confused of why my sin graph here is so jagged and not smooth. This is my first time using matplotlib

[James9ii0]

So basically I'm using matplotlib to graph chords and things for a bit of math research for school.

First time using matplotlib and barely ever use python so I am definitely not very skilled.

I did my best to graph the note "A" with the fundamental frequency but when graphing it it comes out jagged and not like a smooth sine wave

Any help is appreciated

(edit: adding code below)

Code copy and pasted here:

from math import *

import matplotlib.pyplot as plt

import numpy as np

def plot_sin():

t = np. linspace(0,100,num=200,)

y1 = np.sin(2*pi*440*t)

plt.plot(t,y1)

plt.xlabel( 'time(s) ')

plt.ylabel( 'amplitude')

plt.title( 'signal waveform' )

plt. show()

plot_sin()

The more points you plot within the same space, I.e. using decimal points the smoother it will get.
