## What is spline interpolation explain briefly?

Cubic spline interpolation is a way of finding a curve that connects data points with a degree of three or less. Splines are polynomial that are smooth and continuous across a given plot and also continuous first and second derivatives where they join.

**Why do we use spline interpolation?**

Spline interpolation is often preferred over polynomial interpolation because the interpolation error can be made small even when using low-degree polynomials for the spline.

### Why is spline interpolation better?

Its (Splines) advantage is higher accuracy with the less computational effort. It is a computationally efficient method and the produced algorithm can easily be implemented on a computer.

**What are splines used for?**

Splines are grooves or teeth on a shaft that match up with grooves or teeth on another component to transmit torque. Splines are generally used when both linear and rotational motion is desired. There are various types of splines used for numerous industrial applications.

## What is spline in math?

A spline is a continuous function which coincides with a polynomial on every subinterval of the whole interval on which is defined. In other words, splines are functions which are piecewise polynomial. The coefficients of the polynomial differs from interval to interval, but the order of the polynomial is the same.

**What is the difference between interpolation & curve fittings?**

Interpolation is to connect discrete data points so that one can get reasonable estimates of data points between the given points. Curve fitting is to find a curve that could best indicate the trend of a given set of data.

### What are the difference between interpolation and extrapolation?

Extrapolation refers to estimating an unknown value based on extending a known sequence of values or facts. To extrapolate is to infer something not explicitly stated from existing information. Interpolation is the act of estimating a value within two known values that exist within a sequence of values.

**What are the types of spline?**

Types of Spline Shaft:

- (1) Parallel: Parallel spline shaft would have ridges or teeth that have a square profile.
- (2) Involute: This kind has tapered ridges along the shaft, which help in lowering the stress concentrations during gear operation.
- (3) Crowned:
- (4) Serrations:
- (5) Helical:

## How are splines formed?

Serrations and involute splines can be achieved through the milling process. During the process, the cutting tool rotates axially along the surface of the shaft to remove the unwanted particles forming the splines.

**What are uses of spline?**

Splines are used in graphics applications to design curve and surface shapes, to digitize drawings for computer storage, and to specify animation paths for the objects or the camera in a scene.

**What is the difference between interpolation and curve fitting?**

Whereas interpolation is used when we assume that all data points are accurate and we want to infer new intermediate data points – curve fittingis used when we want to match an analytical (or symbolic) model to a set of measurements which may contain some error.
