Calculate double integrals numerically using midpoint, trapezoidal, and Simpson's rule methods
Supported: +, -, *, /, ^, sin, cos, tan, ln, log, sqrt, abs, exp, pi, e
Range: 10-500 subdivisions
Evaluates function at the center of each rectangular subdivision. Simple and generally reliable.
Uses linear interpolation between grid points. Good for smooth functions.
Uses quadratic interpolation. Most accurate for polynomial functions but requires even subdivisions.
Use parentheses for complex expressions: (x+1)*(y-2)
Higher subdivisions give more accurate results but take longer to compute
