## How small does an angle have to be to use small angle approximation?

A ‘small angle’ is equally small whatever system you use to measure it. Thus if an angle is, say, **much smaller than 0.1 rad, it will be much smaller than the equivalent in degrees. More typically, saying ‘small angle approximation’ typically means u03b8u226a1, where u03b8 is in radians; this can be rephrased in degrees as u03b8u226a57u2218.**

## Are small angle approximations in the formula booklet?

Small angle approximations are given in the formula booklet. They can be used in proofs particularly differentiation from first principles (see First Principles Differentiation Trigonometry.

## What is meant by small angle approximation in simple pendulum?

Small Angle Approximation and Simple Harmonic Motion With the assumption of small angles, **the frequency and period of the pendulum are independent of the initial angular displacement amplitude. All simple pendulums should have the same period regardless of their initial angle (and regardless of their masses).**

The small angle approximation states: For small enough angles, **the tangent of an angle is equal to the angle itself (when measured in radians).**

## What does trigonometric mean in math?

Trigonometry is a branch of **mathematics that studies relationships between the sides and angles of triangles. The word trigonometry is a 16th-century Latin derivative from the Greek words for triangle (trigdnon) and measure (metron).**
