Ex 34, 8 Find the general solution of the equation sec2 2x = 1 – tan 2x sec2 2x = 1 – tan 2x 1 tan2 2x = 1 – tan2x tan2 2x tan2x = 1 – 1 tan2 2x tan2x = 0 tan 2x (tan2x 1) = 0 Hence We know that sec2 x = 1 tan2 x So, sec2 2x = 1 tan2 2x tan 2x = 0 taFree trigonometric identities list trigonometric identities by request stepbystep This website uses cookies to ensure you get the best experience By using this website, you agree to our Cookie Policy Learn more Accept Solutions Graphing Practice;Trig Use the fundamental identities to simplify the expression cot beta sec beta I used 1tan^2u=secu since cot is the inverse of tan I flipped the tangent, then so it was 1 (1/tan) But the book's answer is the cosecant of beta Ex 3 4 8 Find General Solution Of Sec 2 2x 1 Tan 2x Teachoo Trig identities 1+tan^2x
