Question 753772: Someone help me with this .This is a textbook example but i dont understand how the text book got the answers for these.Can someone explain please it would be greatly appreciated.Thanks.
A point P(X,Y) is shown on the unit circle corresponding to a real number t.Find the values of the trigometric functions at t for
1.)P(-15/17,8/17)
2.)P(24/25,-7/25)

You can put this solution on YOUR website! A point P(X,Y) is shown on the unit circle corresponding to a real number t.Find the values of the trigometric functions at t for
1.)P(-15/17,8/17)
This is a reference right triangle in quadrant II, with the following:
adjacent side=-15
opposite side=8
hypotenuse=17
sin(t)=8/17
cos(t)=-15/17
tan(t)=-8/15
csc(t)=17/8
sec(t)=-17/15
cot(t)=-15/8
..
2.)P(24/25,-7/25)
This is a reference right triangle in quadrant IV, with the following:
adjacent side=24
opposite side=-7
hypotenuse=25
sin(t)=-7/25
cos(t)=24/25
tan(t)=-7/24
csc(t)=-25/7
sec(t)=25/24
cot(t)=-24/7
