We can start with the identity sin 2 (x)cos 2 (x)=1 If we divide through the equation by cos 2 (x), we get sin 2 (x)/cos 2 (x) cos 2 (x)/cos 2 (x) = 1/cos 2 (x) If we look at the left hand side of the equation sin 2 (x)/cos 2 (x) is equal to tan 2 (x), and cos 2 (x)/cos 2 (x) is equal to 1 (as it is divided through by itself), the left hand side becomes tan 2 (x) 1 Now if we look at theClick here👆to get an answer to your question ️ Show that tan^4theta tan^2theta = sec^4theta sec^2thetaProve that 1 tan^2 x = sec^2 x We know that tan x = sin x/cos x and so tan 2 x = sin 2 x/cos 2 x We also know that sin 2 x cos 2 x = 1 because this is a Pythagorean identity We can rewrite the left hand side as (cos 2 x sin 2 x)/cos 2 x because 1 can be rewritten as cos 2 x/cos 2 x

An expansion of Pythagoras' Identity18/05/10 · Since tan^2(x) 1 = sec^2(x) is an equation derived from sin^2 x cos^2 x = 1 (divide everything by cos^2 x), and since from that equation you can find that tan(x) = square root of (sec^2(x) 1), that means d/dx of tan(x) = d/dx of squareroot of (sec^2(x) 1) = (1/2)(sec^2(x) 1)^(1/2) times d/dx of (cos^2(x) 1) or you can take the derivative of sec^2(x) 1 in tandemFree math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with stepbystep explanations, just like a math tutor

As there is no way to immediately integrate tan^2(x) using well known trigonometric integrals and derivatives, it seems like a good idea would be writing tan^2(x) as sec^2(x) 1 Now, we can recognise sec^2(x) as the derivative of tan(x) (you can prove this using the quotient rule and the identity sin^2(x) cos^2(x) = 1), while we get x when we integrate 1, so our final answer is tan(x)Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with stepbystep explanations, just like a math tutorDani Aug 13, 15 cos 2 x = 2 cos 2 x − 1 tan 2 x 1 = sec 2 x 1 cos 2 x = 2 cos 2 x = sec 2 x 2
