The four rules for the derivatives of the tangent, cotangent, secant, and cosecant can be used along with the rules for power functions, exponential functions, and the sine and cosine, as well as the sum, constant multiple, product, and quotient rules, to quickly differentiate a wide range of different functions. Graphing ALL 6 trig functions [sin, cos, tan, sec, csc, cot] step-by-step. \cos (\theta) = 0 cos() = 0. If you give each function an angle as input (the domain is the possible range of values for the input), you will get an output value (the range). The domain of the secant function is R - (2n + 1)/2 and the range is (-,-1] U [1, ). So they "cancel" each other under composition of functions, as follows. The Graph of cot(x) function. Range of Tangent Function: All the real numbers. The graph of the secant function is as follows: k k. Each trigonometric function has an inverse function of it, whether it is sine, cosine, tangent, secant, cosecant and cotangent. Domain and Codomain of the Secant Function Since at then the function is not defined at these points. As 1 cos x 1, y = sec x does not take values in (1, 1) .Thus, the range of the secant function is (,1] [1, ) . We also showed how to use the Chain Rule to nd the domain and derivative of a function of the form k(x) = 1 g(x); where g(x) is some function with a derivative. Since for all integer n, cos( 2 + n) = cos( 2n +1 2 ) = 0, the domain of f is all real numbers except for x = 2n + 1 2 for all integer n. I hope that this was helpful.
