yes, that is what I said. Cot 45 = 1/tan 45 = 1 I also did the other trig functions of 45 because I am sure you will need them.

Damon, when I opened the page and started to answer this question, I left it alone to watch the end of the WorldCup football game, and when I resumed I did not refresh the page, thus did not see your answer was already posted.

Maths - Trig
Usually my first step in proving any trig identity is taking an arbitrary angle to see if it makes it true, say 45 degrees. Picking up from Damon's first line, your equation is tanx + cotx = 2/sinx for x = 45 degrees LS = 1+1 = 2 RS = 2/.707 which is not LS so the equation is ...

Algebra2/Trig
Horizontal axis means of form: (y-k)^2 = 4p(x-h) if the vertex is at the origin (h,k) = (0,0) y^2 = 4 p x 36 = 4 p (4) p = (9/4) so y^2 = 9 x

No, trig :) Draw a sketch, h is height of balloon over bridge tan 71 h/270 so h = 270 tan 71 = 784 then tan 54 = h/x where x is hor dist to other end from balloon x = h/tan 54 = 570 so total length = 270 + 570 = 840 meters

x/2 = 2pi/3 yields a unique solution of x = 4pi/3 Does this answer come from some trig equation? Your subject title suggests that. In that case find the period of the trig function, then add k(period) to 4pi/3, k an integer.

cos(x)[2sin(x)+1]=0 so zero when cos x = 0 or when sin x = -1/2 note this is just like factoring a quadratic x^2 - 4x + 3 = 0 (x-3) (x-1) = 0 satisfied when x-3 = 0 , so x = 3 and when x-1 = 0 so x = 1
