sec x = 1/cos x
csc x = 1/sin x
cot= 1/tan x
tan x = sin x/cos x
cot x = cos x/sin x
Domain and Range
Domain: The domain of a function is the set of all possible input values (often the "x" variable), which produce a valid output from a particular function. It is the set of all real numbers for which a function is mathematically defined.
Range: The range is the set of all possible output values (usually the variable y, or sometimes expressed as f(x)), which result from using a particular function.
