Theres a syntax error in your code. Also no, I mean that I need to write a cos function that will look like my graph. Or cos^2x function. Both are okay for meMerlin3189 said:Do you mean
change t = np.cos(r)+10
to t = np.(cos(r) + 1) edit: or t = 12*(np.cos(r) + 1) ; if np. is not the amplitude
so that the lower extreme is on the y=0 axis?
r = np.arange(0,400,0.4)
t = (11*np.cos(r/28.7))+11
plt.plot(r,t)
A cos function in Python is a mathematical function that calculates the cosine value of a given angle. It is a part of the math module in Python that provides access to various mathematical functions, including trigonometric functions such as sine, cosine, and tangent.
To graph a cos function in Python, you need to import the matplotlib library, which provides a wide range of tools for creating graphs and charts. Then, you can use the plt.plot() function to plot the cos function with the desired inputs and display it using the plt.show() function.
The syntax for graphing a cos function in Python is as follows:
import matplotlib.pyplot as plt
x = np.linspace(start, stop, num)
y = np.cos(x)
plt.plot(x, y)
plt.show()
Here, start and stop represent the start and end points of the x-axis, and num represents the number of points to be plotted. The np.linspace() function creates an evenly spaced array of numbers between the start and stop values.
There are several ways to customize the graph of a cos function in Python. You can change the color, line style, and width of the graph by passing in the desired parameters to the plt.plot() function. Additionally, you can add a title, labels for the x-axis and y-axis, and a legend using the plt.title(), plt.xlabel(), plt.ylabel(), and plt.legend() functions, respectively.
Yes, you can graph multiple cos functions on the same plot in Python by calling the plt.plot() function multiple times with different inputs for x and y. You can also customize each plot individually by passing in different parameters to each plt.plot() function. Additionally, you can use the plt.subplot() function to create subplots for each cos function.
