Formulas
f(x) = 2 sin(2x)
h(x) = cos(2x)
m(x) = arccot(x)
(f + h)(x) = f(x) + h(x)
(f/h)(x) = f(x)/h(x)
Domain of cosine: cos(2x) = 0 for x = π/4 + nπ/2
Theorems
The domain of a sum of functions is the intersection of the domains of the individual functions.
The domain of a quotient of functions excludes points where the denominator is zero.
Suitable Grade Level
