(sec(x)tan(x)): The product of sec(x) and tan(x), which represents the rate of change of both functions combined.
(csc(x))': The derivative of csc(x), which represents the rate of change of the cosecant function with respect to x.
The derivative of cot(x), which represents the rate of change of the cotangent function with respect to x.
