Web16 aug. 2024 · sin θ = 1/cosec θ. cos θ = 1/sec θ. tan θ = 1/cot θ. All these are taken from a right-angled triangle. When the. height and base side of the right triangle are known, we. can Jnd out the sine, cosine, tangent, secant, cosecant, and cotangent values using trigonometric formulas. The. WebAll trigonometric identities are cyclic in nature which means that they repeat themselves after a period. This period differs for different trigonometry formulas on periodic identities. For example, tan 30° = tan 210° but the same is not true for cos 30° and cos 210°. ionia michigan register of deeds
