What are the properties of CSC, COS,SEC,TAN, AND COT. Meaning whats the domain, range, continuity, symmetry, bounded,asymptote, and max/min. I know the domain for Sin is all real numbers. Any help can help!! Please helpp

The domain of cos and tan are also all real numbers.
The range of cos and sin are both [-1,1]
The range of tan is all real numbers.
The domain of tan is all real numbers except multiples of (2x+1)*pi/2. In other words, at pi, -pi, 3pi/2, tan(x) is not defined. (Basically, wherever cos(x) = 0.) It is asymptotic to these lines.
Because the other three are defined as inverses, you are going to have to take into account what happens when something is 0. When cos(x) = 0, what happens to sec(x). When tan(x) goes asymptotic, what is the cot(x).

If you know what cosecant, cosine, secant, tangent and cotangent means, it will be easy. If you don't know, look it up!
