WebLet us assume that we want to find the exact value of f(x), where f is any of the six trigonometric functions sine, cosine, tangent, cotangent, secant and cosecant. To find the exact value of f(x), we suggest the following steps: 1 - If the angle x is negative, we first use a formula for negative angles such as sin (- x) = - sin (x), cos (- x ...
WebThis is also the relationship between all the other cofunctions in trigonometry: tan (θ)=cot (90°-θ), sec=csc (90°-θ). One other way to think about the relationship between a function and its cofunction is to think about the unit circle: your x-distance is described by cos (θ), and your y-distance described by sin (θ). pub meals newtownWebWhat is the unit circle definition of the trigonometric functions?
