Best ResponseYou've already chosen the best response.0The expression is a bit confusing. Can you rewrite that?

Best ResponseYou've already chosen the best response.0Did you mean \[(\frac{5}{7}, \frac{2\sqrt6}{7})\]

Best ResponseYou've already chosen the best response.0Any point on the unit circle can be represented by \[(\sin(t), \cos(t))\]. The angle t isn't important here. What this tells us is that the current angle has a sine of (5/7). And we know that csc(t) = 1/sin(t), so all we do is flip the sine value to get csc(t) for the t in question = 7/5

Best ResponseYou've already chosen the best response.0so I need to study the trig functions of sin cos, and tan, and then flip for cot, csc, and sec

Best ResponseYou've already chosen the best response.0Make sure you know which one is the inverse of which: csc(t) = 1/sin(t) sec(t) = 1/cos(t) cot(t) = 1/tan(t) just in case

Best ResponseYou've already chosen the best response.0So......if I have this P on this unit circle that corresponds to a real number (t) and the [sqrt:7/4, 3/4] and I need to find cot(t) the answer would be the square root of 7/3 right?

Best ResponseYou've already chosen the best response.0Depends on where you mean to have parenthesis, but even then, still not quite: (sqrt(7))/3 = tan(t). So cot(t) is the inverse of that: 3/(sqrt(7))
