0.25/1 points 1 Previous Answers SAigTrig4 6.1060 My Notes point determined by t is the porte-on the unit cird. Find the terminal point determined (a) t (x, y)-7 433 (b) 4+t (c) -t 7733 (d) t- (x,y) 77 Need Help? ReadR

Solution

x=cost=4_/7 , y=sint= 33_/7

(a)

x=cos(-t)=cost=4_/7 , y=sin(-t)=-sin(t)=- 33_/7

point (x,y)=(4_/7 ,-33_/7)

(b)

x=cos(4+t)=cost=4_/7 , y=sin(4+t)=sin(t)= 33_/7

point (x,y)=(4_/7 ,33_/7)

(c)

x=cos(-t)=-cost=-4_/7 , y=sin(-t)=sin(t)= 33_/7

point (x,y)=(-4_/7 ,33_/7)

(d)

x=cos(t-)=-cost=-4_/7 , y=sin(t-)=-sin(t)= -33_/7

point (x,y)=(-4_/7 ,-33_/7)
