Find and if and terminates in quadrant
WebQuestion: Find \( \sin 2 x, \cos 2 x \), and \( \tan 2 x \) if \( \tan x=\frac{1}{2} \) and \( x \) terminates in quadrant I. WebMay 5, 2024 · Now, we can calculate all the trig ratios for angle x: sin x = 3/√13 and cos x = 2/√13. Since angle x terminates in quadrant III, sin x and cos x are both negative: sin x = - 3/√13 and cos x = -2/√13. Using our trig identities: sin 2x = 2 sin x cos x = 2 (-3/√13) (-2/√13) = +12/13. cos 2x = (cos x)^2 - (sin x)^2 = 4/13 - 9/13 = -5/13.

WebJul 5, 2024 · Let $A$ be in the fourth quadrant and let $\sec (A) = \dfrac {13} {5}$, Let $B$ be in the third quadrant and let $\csc (B)=\dfrac {-5} {3}$. Find $\sin (A + B)$ and determine in which quadrant $A + B$ terminates. $\sec (A) = \dfrac {13} {5} \Rightarrow \cos (A) = \dfrac {5} {13}$ $\csc (B) = \dfrac {-5} {3} \Rightarrow \sin (B) = \dfrac {-3} {5}$ Webthird quadrant is the quadrant on the negative x axis side and negative y axis side, so both x and y are negative here. 270 degrees/ 3pi/2 radians is the negative y axis, so x is 0 and y is negative. for the axes specifically, if …
