Web`csc x = 1 / sin x` `cot x = 1 / tan x = cos x / sin x` First, we need to figure out the value of `sin x`. Since `cos x = -1/2` and `x` is in the third quadrant, we know that `sin x` is negative. Using the identity `sin^2x + cos^2x = 1`, we can solve for `sin x`: `sin^2x + (-1/2)^2 = 1` `sin^2x = 3/4` `sin x = -sqrt(3)/2` WebID: A 1 F.TF.A.2: Finding the Terminal Side of an Angle 1b Answer Section 1 ANS: II If sin 0, then the terminal side of lies in either Quadrant I or II.

Web2 nov. 2024 · cosec is negative in 3rd Quadrant. Therefore cosec (180° + θ) = – cosec θ 225° lies in 3rd Quadrant. cosec (225°) = cosec (180° + 45°) cosec (225°) = – cosec (45°) cosec (225°) = – √2 (Since, cosec (45°) = √2) Therefore, the value of cosec (225°) is -√2.
