Trigonometry Cheat Sheet for definitions, properties, and identities of circular & hyperbolic functions and their inverses. θ, φ, x, and y are all real numbers, with θ and φ in radians. z is a complex variable of the form a+bi, where a and b are real numbers, and i is the imaginary unit:
i=√(-1). C=Circular, H=Hyperbolic, I=-Inverse.
