trigonometric

基本解释

I’m writing a book about trigonometric and exponential functions.
我在写一本关于三角和指数功能的书。
The inverse hyperbolic trigonometric functions — acosh, asinh, and atanh — are not yet included.
还没有包含反双曲三角函数 — 反双曲余弦、反双曲正弦和反双曲正切。
Babbage intended to use the Difference Engine to compute trigonometric tables, which sailors (among others) used to compute the results of trig functions.
巴贝奇打算使用差分机计算三角函数表，海员（还有其他人）用这个表来解三角函数方程。

All right. And of course, there's trigonometric identities you know from high school.
好的,当然了,你们高中就学过了三角恒等式

Casio has redesigned the ClassPad series' software keyboard to make this new model easier to use, organizing functions to correspond to three levels of learning difficulty, beginning with basic functions used by everyone like fractions, square roots, and trigonometric functions, then advanced functions like differential calculus, complex compound numbers, and sigma calculations, and finally even more advanced calculations including piecewise and user-defined formulas.
