所以，在小角度近似值中，就等于mg, that, I, can, make, t, the, same, as, mg。，这是近似值，但是依然写等于号。

So I simply have, in my small-angle approximation, t It's approximately, but I still put an equals sign there.

现在我们要，取近似值，我们将要取的，这个近似值，是我们经常在，物理上看到的-，我们称之为，小角度近似值。

And now we're going to make some approximations, and the approximations that we will make which we will often see - in physics when something oscillates — what we call the small-angle approximations.

所有自然吸气发动机最大功率为170hp/6000rpm（近似值125kw/6000rpm）,最大扭矩170lb-ft/4400rpm（近似值230Nm/4400rpm）,并且有5速手动变速器和4速自动变速器可供选择。

The all-natural X engine delivers 170 horsepower at 6000 rpm and 170 lb-ft of torque at 4400 rpm, and can be had with either a five-speed manual or four-speed automatic.

All right. I tried it on 2, I surely didn't expect a precise and exact answer to that but I got something, and if you square this, you'll find the answer kept pretty darn close to 2.

好，我试试求2的平方根,我当然不希望得到一个完全准确的答案了,但是我得到了一个近似值，试试将这个数平方一下,你会发现结果和2相当接近。
