WebThe point at which the terminal side of the angle intersects the unit circle has an x-value of cos⁡(θ) and y-value of sin⁡(θ). Thus, on the unit circle, cosine and sine can be defined as: For tan⁡(θ), x cannot be equal to 0. Cosecant, secant, and cotangent are the reciprocals of sine, cosine, and tangent respectively, and are defined as: WebBy definition of the tangent: tangent is the ratio of sine to cosine. Therefore, the sign of the tangent will be positive in the quadrants where the sine and cosine have the same signs. …
