Move the mouse around to see how different angles (in radians or degrees) affect sine, cosine and tangent.In this animation the hypotenuse is 1, making the Unit Circle, which is like a map for trigonometry.Notice that the adjacent side and opposite side can be positive or negative, which ...
1.So what's the sine of 30? sin30°是多少? 实 们写到这里? 「可汗学院:物理」 2.What's the sine of 30 degrees? sin30度等於多少? 「可汗学院:物理」 3.But let me go back to these sines, cosines and logarithms. 但让们再来说说正弦、余弦和对数函数。 「 Big Think超级思想」 4.Opposite...

The phase shift between the sine and cosine functions is precisely 90 degrees, meaning that sine can be thought of as a cosine wave shifted 90 degrees to the right, and vice versa. This property is used in analyzing waves and oscillations, where the phase difference can have physical signific...
The result is pretty close to the sine of 30 degrees, which is Carrying out the computations using a few more terms will make the result even closer to the actual answer. And the closer the angle measure is to 0, the more quickly the value of the sine or the cosine meets the exact ...
