For the same value of t as in exercise 7, what are the coordinates of P(π – t)?
Value of t is (2 π /3) a. (3/5, 4/5)
b. (-4/5, 3/5)
c. (-4/5, -3/5)
d. (4/5, -3/5)

Question

For the same value of t as in exercise 7, what are the coordinates of P(π – t)? 
Value of t is (2 π /3) a. (3/5, 4/5) 
b. (-4/5, 3/5) 
c. (-4/5, -3/5) 
d. (4/5, -3/5)

anonymous · Answer

Exercise 7 says "If P(t) has coordinates (4/5, 3/5), find the coordinates of P(t + π)."

phi · Answer

do they say what P(t) is ?   e.g. a graph or an equation ?

anonymous · Answer

They don't say.

anonymous · Answer

dont get it

phi · Answer

Do the previous questions ask about P(t) ?  what is the first time they mention P(t) and what do they say  about it?

anonymous · Answer

There are no previous ones. This has to do with Sinusoids and the Other Trig Functions, if that helps

phi · Answer

OK, I am guessing that P(t) is on a circle:
|dw:1364514604734:dw|
