We will use the following trigonometric formula to prove the formula for tan 2x tan (a b) = (tan a tan b)/ (1 tan a tan b) We have tan 2x = tan (x x) = (tan x tan x)/ (1 tan x tan x) = 2 tan x/ (1 tan 2 x) Hence, we have derived the tan 2x formula using the angle sum formula of the tangent functionWe can prove the double angle identities using the sum formulas for sine and Shivam Mishra, Meritnation Expert added an answer, on 26/7/16 Shivam Mishra answered this Dear Student, Please find below the solution to the asked query We have f 2 tanx 1 tan 2 x = cos 2 x 1 sec 2 x 2 tanx 2 = cos 2 x 1 2 1 cos 2 x 2 sinx cosx = cos 2 x 1 2 1 2 sinx cosx cos 2 x = cos 2 x 1 2 1 sin 2 x cos 2 x = 2 cos 2 x 1 1 2 1 sin 2 x cos 2 x = 2 cos 2 x 2 1 sin 2 x cos 2 x f 2 tanx 1 tan 2 x = 1 sin 2 x We know that 2 tanx 1 tanDo NOT divide by sin bc it can equal zero to find a side, you can divide by sin to find theta
Using the tan1 x convention may lead to confusion about the difference between arctangent and cotangent It turns out that arctan and cot are really separate things cot(x) = 1/tan(x) , so cotangent is basically the reciprocal of a tangent, or, in 149 अगर , तो का मूल्य , तो के बराबर है int e^ (x) ( (2 tanx)/ (1tanx)cot^ (2) (x (pi)/ (4)))dx is equal to Updated On 299 To keep watching this video solution for FREE, Download our App Join the 2 Crores Student community now!
