Find the derivative of the elementary function using sympy.
from sympy import * #Imoprt all features from the sympy library
sym.init_printing() #Format output
x=Symbol('x') #letter'x'Is defined as the variable x
y=Symbol('y') #letter'y'Is defined as the variable y
#differential
diff(sin(x),x) #sin(x)Differentiation of
diff(exp(x),x) # e^Differentiation of x
#Higher derivative
diff(x**4+x**3,x,2) # x^4+x^2nd derivative of 3
#Partial differential
diff(x**2+x*y+2*y**2,x) # x^2+xy+2y^Partial derivative of 2 by x
#When leaving a differential symbol
Derivative(y(t),t)
From top to bottom, it is as follows.
