The … Web29 de jan. de 2024 · On the unit circle, the sine is the y value of the point t and the cos is the x-value of the point t, while tan is the slope at the point t. In this case, the y value given is 35/37, which is sin (t). The x - value given, -12/37, is cos (t). The tan is the slope or alternatively, the y value/ x value = sin t / cos t = 35/37 / -12/37 = -35/12.

When the angle is between 0 and 90°, we get back the previous definitions. It also leads to the polar coordinate system, where the minus sign is never negligible, and the sine-cosine interpretation should give back the x-y components.
