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

而更复杂的像三角函数之类的操作，可能要超过一分。

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

多项式也可用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.

们可们讨论过的三角导数 关于它，并反过来应用它。

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.

学计算器可使用学记数法、对数和三角函数计算、指数函数、根和幂，及许多人从未听说过的其他冗长复杂的数学术语。
