Visualization of sin , cos and tan graph

Plot of sin , cos and tan graph using Python :

                    In trigonometry , we always hear about sin , cos and tan function also sin is start from zero and cos is start from 1 and ranging and tan function that starts from zero and ranging to infinity . Python and its scientific module such as numpy and matplotlib will help us  to  visualise  those graph.

Source Code :

 import numpy as np  
 import matplotlib.pyplot as plt  
 x=np.linspace(0,15,1000) # value of x  
 y=np.sin(x)  
 y1=np.cos(x)  
 y2=np.tan(x)  
 """ ###### PLOT SIN AND COS GRAPH ###### """  
 plt.subplot(1,2,1)  
 plt.plot(x,y,c='b',label = "sin (x)")  
 plt.plot(x,y1,c='r',label = "cos (x)")  
 plt.axhline(0 ,color="black")  
 plt.legend(loc='best' , prop={'size':12})  
 plt.xlim(0,15)  
 """ ###### PLOT TAN GRAPH ##### """  
 plt.subplot(1,2,2)  
 plt.plot(x,y2,c='c', label = "tan (x)")  
 plt.ylim(-10,10)  
 plt.axhline(0 , color="black")  
 plt.legend(loc='best' , prop={'size':12})  
 plt.suptitle("Visualization of sin , cos and tan graph",fontsize=18,color='b',fontstyle ="italic")  
 plt.show()
