THIS volume, dealing mainly with analytical trigonometry, provides an excellent school course for senior scholars. It embraces the logarithmic, exponential, and hyperbolic functions expansion in power ...

Mastering degree-radian conversions is crucial for trigonometry and calculus. Radians simplify mathematical formulas, especially in calculus where trigonometric function derivatives rely on radian ...

So many books on trigonometry are published that, when a new one makes its appearance, especial characteristics are naturally looked for. The present volume is much larger than usual, but it surveys a ...
