The six basic trigonometric identities are the equations of the six trigonometric functions. Those trig functions are sine = O/H, cosine = A/H, tangent = O/A, secant = H/A, cosecant = H/O, and cotangent = A/O, where H is the hypotenuse, O is the opposite side, and A is the...

Many equations appear quadratic in form. We can use substitution to make the equation appear simpler, and then use the same techniques we use solving an algebraic quadratic: factoring, the quadratic formula, etc. We can also use the identities to solve trigonometric equation. We can use substitu...
Trigonometry identities:are equations that show relationships between trigonometric functions and are often used to simplify trigonometric expressions. These identities are true for every value of the variables that are included. Some of the Fundamental Trigonometric Functions: ...
No need to dive right into memorizing geometric proofs andtrigonometric identities. But that's exactly what high schools have you do.───不必去钻拾记住几何上的证明和三角恒等式,虽然那确实是高中学校要求你必须去做的。 Trigonometric identities and simple equations───三角恒等式和简单的三角等式 ...
