WebbIn geometric optics, the paraxial approximation is a small-angle approximation used in Gaussian optics and ray tracing of light through an optical system (such as a lens ). [1] [2] A paraxial ray is a ray which makes a small angle ( θ) to the optical axis of the system, and lies close to the axis throughout the system.

WebbNow everyone also knows that the small angle approximation for cos is just the truncated ( O ( θ 3)) Taylor series, and it's fairly easy to see that for small θ: cos ( θ) = 1 − sin 2 ( θ) ≈ 1 − θ 2 which ≈ 1 − θ 2 2 by the binomial expansion for 1 − x ...But my students don't know Taylor series or binomial expansions. WebbSmall Angle Approximations Example When θ is small, find the approximate value of: sin 2θ + tan θ 2θ cos 4θ -1 θ sin 2θ Example a) Show that, when θ is small, sin 5θ + tan 2θ - cos 2θ ≈2 θ 2 +7θ-1 b) Hence state the approximate value of sin 5θ + tan 2θ - cos 2θ for small values of θ .

WebbIf you study the derivation of the motion of the pendulum, at some point the angle is assumed to be small so that the angle (measued in radians) is equal to the sine of the angle. This is true only for small angle and therefore small displacement A = tan A = sin A for small A 2 comments ( 6 votes) Esha 6 years ago WebbThe small angle approximation can be used to make it easier to work with trigonometric functions when looking at angles close to 0 rad. The small angle approximation has to be worked out in radians. The three formulas for small angle approximation are: sin θ ≈ θ tan θ ≈ θ cos θ ≈ 1 - θ 2 2.
