How Do You Integrate 1 Tan2x Sec2x Dx Socratic
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 theAnswer to Solve for x \tan(2x)=1 By signing up, you'll get thousands of stepbystep solutions to your homework questions You can also ask yourOr x = (2n1)pi/6 Answer tan 2x=2tanx÷ {1 (tanx)^2} So, tanx×tan2x is equal to 2 (tan x)^2÷ {1– (tan x)^2} which is again equals to 1 asper the question Therefore, 2 (tan x)^2=1– (tan x)^2, or 3 (tan x)^2=1 , or (tanx)^2=1/3,or tanx=1÷ (3)^1/2= tan30 So x= 30 degree (
