Please help! :) Suppose you start at the point (1,0) on a unit circle and move some distance t along the circle to the terminal point P(8/17,15/17).
What would the exact coordinates of the terminal point be if you had instead moved:
a distance t+π? Terminal Point would be at P( , )
a distance t+2π? Terminal Point would be at P( , )
a distance −t? Terminal Point would be at P( , )
No decimals! Hint: make a sketch of the unit circle and t.

Best ResponseYou've already chosen the best response.0or maybe it's just negative (8/17,15/17)

Best ResponseYou've already chosen the best response.0for 2pi would it be something like this?

Best ResponseYou've already chosen the best response.5No 2pi is a complete circle P would come back to the same place

Best ResponseYou've already chosen the best response.0thanks! :) and for tpi/2 is that just negative?

Best ResponseYou've already chosen the best response.5t  pi/2 will take you back to t + pi/2

Best ResponseYou've already chosen the best response.1\(\color{blue}{\text{Originally Posted by}}\) @sana97 so what if the distance would be t +pi/2? \(\color{blue}{\text{End of Quote}}\) \(\color{blue}{\text{Originally Posted by}}\) @welshfella the same as for t \(\color{blue}{\text{End of Quote}}\) if the distance is t+ pi/2, the coordinates will not be same as that of 't'. I think welshfella mistook it for t +2pi ... dw:1444057152219:dw
