Formula for tangent cosine sine

The tangent function can be expressed in terms of sine and cosine as (\tan(x) = \frac{\sin(x)}{\cos(x)}). This relationship highlights that tangent is the ratio of the sine function to the cosine function for a given angle (x). Additionally, the Pythagorean identity states that (\sin^2(x) + \cos^2(x) = 1), which is fundamental in trigonometry.
