# Mathematics

**Conversions**

Calculates many unit conversions, such as acres to feet, feet to meters, pounds to kilograms, etc.

**Weighted Average**

Calculates the weighted values of selected variables using their individual weights.

**Linear Regression**

Calculates the equation of a straight line that best fits a series of x-y coordinates using least squares. The standard deviation for both x and y and the correlation coefficient are also calculated.

**Polynomial Equation**

Calculates the coefficients of a polynomial equation that exactly fits up to 10 known x-y coefficients.

**Triangle Solutions**

Calculates solutions for the five standard triangle problems; Side-Side-Side, Angle-Side-Angle, Side-Angle-Angle, Side-Angle-Side, and Side-Side-Angle.

**Interpolation**

Interpolates values between two known x-y coordinate pairs. The program is able to interpolate either the x or y coordinate if the other is known.

**Linear Simultaneous Equations**

Calculates the solution of up to eight linear simultaneous equations.

**Non-Linear Simultaneous Equations**

Calculates the solution of up to eight non-linear polynomial simultaneous equations.
