Study Notes

Variable of Integration

The variable of integration is the variable with respect to which the integration is performed.

Integration Symbol

The symbol '$\int$' represents the integral, which is a mathematical operation that calculates the area under a curve.

Integrand

The integrand is the function being integrated, which is the expression that appears inside the integral sign.

Degree of Polynomial

The degree of a polynomial is the highest power of the variable in the expression. To determine the degree of the polynomial in the numerator of the integrand, identify the variable and its highest power.

Bounds of Integration

The bounds of integration are the values that define the limits of the interval over which the integration takes place. They are typically represented as numbers or expressions that represent the starting and ending points of the integration.
