Tan^2x trig identity
Tan^2x trig identity-Now use the identity to replace sin 2 x and write the new integral Now this new integral is a sum of two integrals, the last of which can be evaluated easily using the substitution u = cos(x), like this The first integral is easy, it's just cos(x) The second is easy because of the substitution Now we just back substitute cos(x) for u to get the solution (don't forget the constant) WeAs 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

Proving a trigonometric identity refers to showing that the identity is always true, no matter what value of x x x or θ \theta θ is used Because it has to hold true for all values of x x x, we cannot simply substitute in a few values of x x x to "show" that they are equal It is possible that both sides are equal at several values (namely when we solve the equation), and we might falsely2tan2 x = sec2 x for values of x in the interval 0 ≤ x < 2π We try to relate the given equation to one of our three identities We can use the identity sec2 x = 1tan2 x to rewrite the equation solely in terms of tanx 2tan2 x = sec2 x 2tan 2x = 1tan x from which tan2 x = 1 Taking the square root then gives tanx = 1 or − 1Definitions Trigonometric functions specify the relationships between side lengths and interior angles of a right triangle For example, the sine of angle θ is defined as being the length of the opposite side divided by the length of the hypotenuse The six trigonometric functions are defined for every real number, except, for some of them
