can someone explain me this
for function a) find period, domain, range and label the name of the function in graph. for b) do the same with a but flip the graph reflect to x axis to get the final graph. step by step you calculate and put what you have in graph.
i have problems with finding the domain
domain of sin and cos function is \[(-\infty,\infty)\]because the domain is the range of x , x can "go" from everywhere .
to everywhere . to tan and cot is another topic.
