The domain is all the "x" values for which the function is definied. You could plug any number you wanted to in for "x" in this function, so the answer is "all real numbers".
The range is all the "y" (or in this case "s") values that are answers to the function. By trial and error (plugging in positive numbers, negative numbers, 0, etc.) you can find that the smallest answer you ever get is 4, and you will eventually get all numbers greater than that. So the answer is "s is greater than or equal to 4".

If cot(theta) is undefined, that likely ability the theta = 0, pi,..,n*pi. interior of your constraints, theta should be pi, for the reason that 0 < pi/2, and a couple of*pi > 3*pi/2. the last applications are: sin(pi) = 0, cos(pi) = -a million, tan(pi) = 0 cosec(pi) = undef, sec(pi) = -a million i do not understand what you mean by x,y; and an perspective of pi (one hundred eighty deg) does no longer form a triange, yet lies on the unfavourable x-axis between quadrants IIi and IV
