ok i need a lot of help with trig graphing. lets say that we have an equation like: y = sin1/3(x-pi/4)-2... when ur graphing this equation, how do u no what the increments of the x-axis are going to be on the graph??? yes i do no the basics of the x-axis of sinx like pi/2, pi, 3pi/2, and 2pi... but when the equation gets transformed like the one in my example, how do u figure out what your x-axis is going to be??? obviously pi/2, pi, 3pi/2, and 2pi will be to simple to use when graphing this equation... help please
