"While the early study of trigonometry can be traced to antiquity, the trigonometric functions as they are in use today were developed in the medieval period. The chord function was discovered by Hipparchus of Nicaea (180–125 BCE) and Ptolemy of Roman Egypt (90–165 CE). The functions of sine and versine (1 – cosine) can be traced back to the jyā and koti-jyā functions used in Gupta period Indian astronomy (Aryabhatiya, Surya Siddhanta), via translation from Sanskrit to Arabic a… " - Tan theta expansion

$Small-Angle Approximation Brilliant Math & Science Wiki$

Webtan ( θ) ≈ θ These approximations can only be used when θ is small. Hence why we call them ‘small angle’ approximations. Furthermore, θ must be measured in radians. Here we can see each of the trigonometric graphs plotted against their given approximations. We can see from these plots, the values of θ for which these approximations are good. WebMy question is: Is there any standard technique to expand $\tan^n \theta$ as a sum of tangents or sines or cosines of multiples of $\theta$? EDIT: I noticed that an expansion like what I want doesn't exist even for $\tan^2 \theta$. The best we can do is: $\tan^2 \theta = 1 - 2 {\tan \theta \over \tan 2\theta}$.
