Calculus in Coding: Derivatives and Integrals
Calculus introduces change and accumulation — derivatives and integrals, respectively. Coding calculus enables visualization and numerical approximations essential for understanding continuous functions.
Numerical Derivatives
Using NumPy, approximate derivatives via finite differences:
```python
import numpy as np
Define the function
def f(x):
return np.sin(x)
Create an array of x values
x = np.linspace(0, 2np.pi, 100)
dx = x[1] - x[0]
Numerical derivative
dy = np.gradient(f(x), dx)
import matplotlib.pyplot as plt
plt.plot(x, f(x), label='sin(x)')
plt.plot(x, dy, label='Derivative')
plt.legend()
plt.show()
```
This visualizes the derivative of sin(x), illustrating the concept dynamically.
Numerical Integration
Using SciPy’s quad function:
```python
from scipy.integrate import quad
import numpy as np
Integrate sin(x) from 0 to pi
result, error = quad(np.sin, 0, np.pi)
print(f"Integral of sin(x) from 0 to pi: {result}")
```
Symbolic Differentiation and Integration
SymPy simplifies symbolic calculus:
```python
from sympy import symbols, diff, integrate, sin
x = symbols('x')
f = sin(x)
Derivative
df = diff(f, x)
Indefinite integral
F = integrate(f, x)
print(f"Derivative of sin(x): {df}")
print(f"Integral of sin(x): {F}")
```
Insights:
- Numerical methods approximate derivatives and integrals where symbolic solutions are complex.
- Visualization aids in grasping the behavior of functions under calculus operations.

B = np.array([[5, 6], [7, 8]])
Matrix addition
C = A + B
Matrix multiplication
D = np.dot(A, B)
Determinant
det_A = np.linalg.det(A)
print(f"Sum of matrices:\n{C}")
print(f"Product of matrices:\n{D}")
print(f"Determinant of A: {det_A}")
```
Solving Linear Systems
Using NumPy's linear algebra solver:
```python
System: Ax = b
A = np.array([[3, 1], [1, 2]])
b = np.array([9, 8])
x = np.linalg.solve(A, b)
print(f"Solution vector x: {x}")
```
