Sino math is a non-standard term. Based on the provided reference, it seems to refer to basic trigonometric ratios, specifically sine and cosine, within the context of right triangles.
Here's a breakdown:
-
Sine (sin): The ratio of the length of the opposite side to the length of the hypotenuse in a right triangle. Expressed as:
sin = opposite / hypotenuse -
Cosine (cos): The ratio of the length of the adjacent side to the length of the hypotenuse in a right triangle. Expressed as:
cos = adjacent / hypotenuse
Therefore, if someone is referring to "Sino math", they are likely discussing the fundamental trigonometric functions of sine and cosine in relation to right triangles. It's important to note that this is not a universally accepted or formally defined mathematical term. The standard terminology would simply be "sine" and "cosine".
