Find sin 2x, cos 2x, and tan 2x from the given information. sinx=(5/13), x is 1
According to given question
if x is 1
Sinx = 5/13 Cosx = 12/13 Cosx = 1 - 2 SIn^2x/2 Sinx/2 = Sqrt (1-Cosx / 2) Sinx/2 = 1/Sqrt26 Cosx = 2Cos^2x/2 - 1 Cosx/2 = Sqrt(Cosx +1 / 2) = 5/Sqrt26 Tanx/2
=Sinx/2 / Cosx/2
= 1/Sqrt26 / 5 / Sqrt26
Best Of Luck
sinx=(5/13), x is Quadrant 1Does this change the answer?
in first quaderant all the values of sin ,cos,tan is always positive so answer will be positive
