WebIf $\tan x$ is known, then $\cos x=\dfrac1{\sqrt{1+\tan^2x}}$ and $\sin x=\dfrac{\tan x}{\sqrt{1+\tan^2x}}$ . Basically, given Pythagoras' theorem , if we know the ratio between any two sides, the other two ratios soon follow. Webcosecant, secant and tangent are the reciprocals of sine, cosine and tangent. sin-1, cos-1 & tan-1 are the inverse, NOT the reciprocal. That means sin-1 or inverse sine is the angle θ …
WebThe important sin cos tan formulas (with respect to the above figure) are: sin A = Opposite side/Hypotenuse = BC/AB. cos A = Adjacent side/Hypotenuse = AC/AB. tan A = Opposite side/Adjacent side = BC/AC. We can derive some other sin cos tan formulas using these definitions of sin, cos, and tan functions. We know that sin, cos, and tan are the ... WebMay 13, 2024 · sin = o / h The ratio of the adjacent side of a right triangle to the hypotenuse is called the cosine and given the symbol cos . cos = a / h Finally, the ratio of the opposite side to the adjacent side is called the tangent and given the symbol tan . tan = o / a
