      Pythagorean Theorem tells us that x² + y² = r², therefore r = √ T²+ U². 𝜃 (theta) is used to label a non-right angle. The six trigonometric functions can be used to find the ratio of the side lengths. The six functions are sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot).

      Thus, the six ratios are functions of the variable θand are called the trigonometric functions of the acute angle θ. For convenience, the six ratios have been given names. Historically, these six trigonometric functions have been named sine of theta, cosine of theta, tangent of theta, cosecant of theta, secant of theta, and cotangent of theta.
