sine

Sine 2 theta equals 2 sine theta cosine theta.

sin2θ=2sinθcosθ

So in this problem, we have to solve for sine.

所以在这个问题中 我们要解出正弦值

Coefficients for sine on this monitor cosine on that one.

根据这个荧幕的正弦系数 搭配另一个荧幕的余弦

And so the square of sine plus cosine equals one.

所以sin2 + cos = 1

Mass cancels out, so it's just gravity times sine.

质量抵消了 就是重力乘正弦

Sine is the ratio of the opposite side of the * over the hypotenuse.

正弦值是直角三角形中 对边的长 比上斜边的长的值

Now that we've specified arbitrary angles, we can define their sines and cosines.

既然已经指定了钝角 我们就可以定义它们的正弦和余弦了

So we generate this swept sine wave and we use that to capture the acoustic of the cave.

我们生成这个正弦扫频信号 然后利用它来测定洞穴的声音特性

Okay, I'm gonna grab the others and we'll start searching where you scripted the sine curves of the sound waves.

好吧 我去找其他人来 我们一起找找你到底把声波曲线 写在哪了

Omnia per ipsum facta sunt et sine ipso factum est nihil quod factum est.

万物皆由其所造 无他则无万物
