Webtan (θ) = sin (θ) cos (θ) That is our first Trigonometric Identity. Cosecant, Secant and Cotangent We can also divide "the other way around" (such as Adjacent/Opposite instead of Opposite/Adjacent ): Example: when Opposite = 2 and Hypotenuse = 4 then sin (θ) = 2/4, and csc (θ) = 4/2 Because of all that we can say: sin (θ) = 1/csc (θ) WebThe quotient identities follow from the definition of sine, cosine and tangent. tan θ = sin θ cos θ cot θ = cos θ sin θ Odd/Even Identities An even function is a function where the value of the function acting on an argument is the same as the value of the function when acting on the negative of the argument. Or, in short: f ( x) = f ( − x) how many bushels in a strikeWebSecondly, the identity is tan²θ + 1 = sec²θ, not tan²θ - 1. Maybe this proof will be easier to follow: tan²θ + 1 = sin²θ/cos²θ + 1 = sin²θ/cos²θ + cos²θ/cos²θ = (sin²θ + cos²θ)/cos²θ //sin²θ + cos²θ = 1, which we substitute in. = 1/cos²θ = sec²θ Therefore, tan²θ + 1 = sec²θ.

WebSin (θ), Tan (θ), and 1 are the heights to the line starting from the x -axis, while Cos (θ), 1, and Cot (θ) are lengths along the x -axis starting from the origin. If the acute angle θ is given, then any right triangles that have an angle of θ are similar to each other. This means that the ratio of any two side lengths depends only on θ. http://www.math.com/tables/trig/identities.htm
