This is my program to graph functions and it works great. There is only one problem.
while 1==1:
import numpy as np
import matplotlib.pyplot as plt
print("FUNCTION GRAPHER")
def graph(formula,domain):
x = np.array(domain)
y = eval(formula)
plt.plot(x, y)
plt.show()
def sin(x):
return np.sin(x)
def cos(x):
return np.cos(x)
def tan(x):
return np.tan(x)
def csc(x):
return 1/(np.sin(x))
def sec(x):
return 1/(np.cos(x))
def cot(x):
return 1/(np.tan(x))
formula=input("Function: y=")
domainmin=int(input("Min X Value: "))
domainmax=int(input("Max X Value: "))
graph(formula, range(domainmin,domainmax))
print("DONE!")
When I try a non-linear function, it is not "curvy":
FUNCTION GRAPHER
Function: y=sin(x**2)
Min X Value: 0
Max X Value: 32
I cannot post a pic because I don't have enough reputation yet... but its just really spiky, and the points are only plotted every 1 unit.
