I'm not sure what you want here. tan = sin/cos sec = 1/cos csc = 1/sin cot = 1/tan = cos/sin and cos(theta) = sin(theta + pi/2) sin(theta) = cos(theta - pi/2) Do you just want to plug in the -6 for theta?

If a graph has an inflection point, the slope changes from + to - at that point. (or vice versa). As such, the slope of a tangent line at that point must be zero. NOW, which of those answers are of the form: y = 0x + b or more commonly y = b always, tony
