Best ResponseYou've already chosen the best response.0The sin, cos, and tan values are not affected. Going clockwise around the unit circle gives you negative angle measures; counterclockwise gives you positive angle measures. For example, 7pi/4 is the same as pi/4. Either way, the cos of that angles (by either name) is 0.707 and the sin is 0.707. Does that help?

Best ResponseYou've already chosen the best response.0you mean 7pi/4 and 7pi/4 are equal

Best ResponseYou've already chosen the best response.0No. 7pi/4 and pi/4. Both take you to the 45 degree angle in Quadrant IV. 7pi/4 is 7 increments of 45 degrees, ccw, but 7pi/4 is 7 increments of 45 degrees in the other direction. You travel the same number of degrees, so to speak, but you end up in different places.

Best ResponseYou've already chosen the best response.0so changing the direction also changes the starting point ,instead of being in the first quadrant pi/4 is now in the fourth quadrant

Best ResponseYou've already chosen the best response.0Changing direction doesn't change the starting point. We always start at the bottom of quadrant I. It changes the ending point.

Best ResponseYou've already chosen the best response.0TBates is correct. We always start at 3 o'clock. That's 0 degrees or 0 radians. We then rotate as many degrees or radians as we are given, from that starting point.
