WebCosecant (csc) - Trigonometry function In a right triangle, the cosecant of an angle is the length of the hypotenuse divided by the length of the opposite side. In a formula, it is abbreviated to just 'csc'. Of the six possible trigonometric functions, cosecant, cotangent, and secant, are rarely used. WebThe length of the adjacent of a right triangle with an angle of 45° and an opposite of 3 cm is 3 cm. Remembering the Formula Often, the hardest part of finding the unknown angle is remembering which formula to use. …

Webthe length of the side Opposite angle θ divided by the length of the Hypotenuse Or more simply: sin ( θ) = Opposite / Hypotenuse Example: What is the sine of 35°? Using this triangle (lengths are only to one decimal place): sin (35°) = Opposite / Hypotenuse = 2.8/4.9 = 0.57... The Sine Function can help us solve things like this: WebThese trigonometric identities, commonly called SOHCAHTOA, are: sin x = opposite / hypothenuse; cos x = adjacent / hypothenuse and tan x = opposite / adjacent. Also, the Pythagoras' theorem gives ... WebMay 7, 2024 · We will call the ratio of the opposite side of a right triangle to the hypotenuse the sine and give it the symbol sin . 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 ... port of canada
