Formulas
f(x) = 2sin(2x)
h(x) = cos(2x)
m(x) = cot^{-1}(x)
(f+h)(x) = 2sin(2x) + cos(2x)
(f/h)(x) = (2sin(2x))/(cos(2x))
Theorems
The domain of sine and cosine functions: R (all real numbers)
The domain of inverse cotangent: R (all real numbers)
The domain of a quotient function: Exclude points where the denominator is zero
Suitable Grade Level
Undergraduate Level (Calculus/Pre-Calculus)
