59. Terminal Points Suppose that the terminal point determined by t is the point (. 4) on the unit circle. Find the terminal point determined by each of the following. (a) _t (c) +t (b)-t (d) 2 +t 60. Terminal Points Suppose that the terminal point determined by t is the point (. V7/4) on the unit circle. Find the termi- nal point determined by each of the following. (b) 4m +1 (d) t- (c) _1 DISCUSS DISCOVER PROVE WRITE 61 DISCOVER PROVE: Finding the Terminal Point form/6 Suppose the terminal point determined by t = /6 is P(x,y) and the points Q and R are as shown in the figure. Why are

Explanation / Answer

a. -t= (-3/5,-(7)/4)

b.4+t means t isin first quadrant

So the answer is (3/5,(7)/4)

c.-t

t is in second quadrant where x is negative and y is positive

So the answer is (-3/4,(7)/4)

d.t-=-(-t)

so the answer is(3/4,-(7)/4)
