Final answer:
The subject is Mathematics, specifically trigonometric integration, which involves finding the integral of functions that contain trigonometric functions such as sine and cosine using methods like Simpson's Rule, Riemann Sum, Trapezoidal Rule, or a specialized calculator.
Step-by-step explanation:
The subject of this question is Mathematics, specifically trigonometric integration.
Trigonometric integration involves finding the integral of functions that contain trigonometric functions such as sine and cosine. There are several methods that can be used to solve these integrals, including the use of trigonometric identities and integration techniques like Simpson's Rule, Riemann Sum, and Trapezoidal Rule.
A calculator specifically designed for trigonometric integration can also be used to find the integral.
