Answer:
...so cos t = cot t can only happen when cos t is 0 or sin t is 1. (But sin t = 1 only happens when cos t = 0, so cos t = 0 is enough.)
arccos(0) is pi/2, plus or minus any multiple of pi.
Step-by-step explanation:
cotθ = cosθ
cosθ/sinθ = cosθ
sinθ = 1
θ = π/2
pi also = to 3.14 etc.
Reflecting across the x axis changes the polarity of the y coordinate so the answer would be x
