Calculator 2 - Linear Interpolation
Linear interpolation is one of the simplest ways of interpolation. Linear interpolation determines, from two points (x1,y1) and (x2,y2), what the value of y is at a different point x3. Linear interpolation assumes a linear slope between points 1 and 2 and based on that slope will determine what the value of y would be at another given point x. Obviously a limitation of this method is that it assumes a linear slope, and thus if the parameters do not have a linear relationship the value returned would be incorrect.
