How do you verify the equation is an identity?In mathematics, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined Geometrically, these are identities involving certain functions of one or more anglesThey are distinct from triangle identities, which are identities potentially involving angles but alsoI know that and The next step would then be to say that but now what?

Proving the trigonometric identity $(\tan{^2x}1)(\cos{^2(x)}1)=\tan{^2x}$ has been quite the challenge I have so far attempted using simply the basic trigonometric identities based on the Pythagorean Theorem I am unsure if these basic identities are unsuitable for the situation or if I am not looking at the right angle to tackle this problemUse this substitution you've made in the identity to be proven `tan x(cot x tan x) = 1tan^2 x` Opening the brackets, you'll have`tanx*cotx tan^2x = 1tan^ 2 x`$\tan^2{\theta} \,=\, \sec^2{\theta}1$ The square of tan function equals to the subtraction of one from the square of secant function is called the tan squared formula It is also called as the square of tan function identity Introduction The tangent functions are often involved in trigonometric expressions and equations in square form
