2. Proportionality constants are written within the image: sin θ, cos θ, tan θ, where θ is the common measure of five acute angles. In mathematics , the trigonometric functions (also called circular functions , angle functions or goniometric functions [1] [2] ) are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. Trigonometry (from Greek trigōnon, "triangle" and metron, "measure") is a branch of mathematics that studies relationships between side lengths and angles of triangles. Everything starts with $$\sin(a+b)=\sin a\cos b+\cos a\sin b$$ This is an identity, it holds for all $a$ and $b$. In particular, you're allowed to replace $b$ with $a$, so long as you do it consistently throughout, and you get $$\sin2a=2\sin a\cos a$$ Stop me if you didn't follow this.

Tan^2x-tan^2y=sec^2x-sec^2y and, how do you factor and simplify, cscx(sin^2x+cos^2xtanx)/sinx+cosx . Math please help quick. Which of the following are identities? Check all that apply.
