Drawing a parabola
To draw a parabola (y=x**2):
import matplotlib.pyplot as plt
x = np.linspace(-10, 10, 1000) # Domain from -10 to 10 with 1000 data-pointsplt.title("Parabola $y=x^2$")plt.xlabel("$x$", fontsize=14)plt.ylabel("$y$", fontsize=14)plt.plot(x, x**2)
The output is as follows:
Helper function to draw functions
def my_func(x): return x**2
def plot_function(x_lim, my_func): """ @param x_lim {Array} an array of size two that contains the lower and upper x limits @param my_func {Function} the function that we want to plot """ x = np.linspace(x_lim[0], x_lim[1], 1000) plt.xlabel("$x$", fontsize = 14) plt.ylabel("$y$", fontsize = 14) plt.plot(x, my_func(x))
We can use plot a curve like so:
plot_function([-10,10], my_func)
The output is as follows:
