f((2tanx)/(1tan^2x))=((cos2x1)(sec^2x2tanx))/2 Updated On 227 To keep watching this video solution for FREE, Download our App Join the 2 Crores Student community now!Yes, if the term at the bottom is tan^2 x, you typed tan^x, and I read it as tan x I got the proof, give me a bit of time to type it I'm sorry Mr Reiny you are right it is tan^2x LS= 2tanx/(1tan^2x) 1/(2cos^2x 1) = 2sinx/cosx 1/(1sin^2x/cos^2x) 1/(2cos^2x (sin^2x cos^2x)) Thanks for contributing an answer to Mathematics Stack Exchange!
