Sine and cosine are trigonometric functions that repeat their values in a regular pattern over a specified interval.

• Sine and cosine functions have a period of 2π, meaning they repeat their values every 2π units along the x-axis.

• The sine function oscillates between -1 and 1, reaching its maximum and minimum values at regular intervals.

• The cosine function also oscillates between -1 and 1, but it is shifted by π/2 radians...read more

Integration is the process of finding the antiderivative of a function, while differentiation is the process of finding the derivative of a function.

• Integration involves finding the area under a curve, while differentiation involves finding the slope of a curve.

• Integration is denoted by the symbol ∫, while differentiation is denoted by d/dx.

• Examples of integration include finding the area under a curve using definite i...read more

ODE stands for Ordinary Differential Equation while PDE stands for Partial Differential Equation.

• ODE involves a single independent variable, while PDE involves multiple independent variables.

• ODE solutions are functions of a single variable, while PDE solutions are functions of multiple variables.

• Examples of ODE include Newton's law of cooling, while examples of PDE include heat equation and wave equation.

Dirichlet's condition states that a function must be continuous and have a finite number of discontinuities in a given interval.

• Function must be continuous in the interval

• Function must have a finite number of discontinuities in the interval

• Used in Fourier series analysis
