And more complex operations, like a trigonometric function, could take over a minute.

而更三角函数之类操作，可能要超过一分钟。

Polynomials could also be used to approximate logarithmic and trigonometric functions, which are a real hassle to calculate by hand.

多项式也可以于近似对数和三角函数些函数手算相当麻烦。

You can take the trigonometric derivatives that we talked about, and do those backward, too.

我们可以取我们讨论过三角导数 关于，并反过来应。

These beasts can work with scientific notation, logarithmic and trigonometric calculations, exponential functions, roots and powers, and other long complicated mathematical terms that many people have never even heard of.

科学计算器可以使科学记数法、对数和三角函数计算、指数函数、根和幂，以及许多人从未听说过其他冗长数学术语。
