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?

Proportions are about noticing patterns: First write the proportion as top/bottom, top/bottom 6 ..... x --- = ---- 18 ... 27 Notice if you go from 6 to 18, that's multiplying by 3. So to go from x to 27, that should also be multiplying by 3. x...

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

1. speed=distance/time, therefore speed x time=distance and time=distance/speed. The units of speed are already measured in km, the same as the distance of the galaxy, and the time is measured in years. We therefore don't have to worry about the units...
