I need an explanation for this question. I have no idea how to start.
Explain why we must have \ot^2 x + 1 = csc^2x for any x such that x is not an integer multiple of 180 degrees.
Thanks
THanks, I figured out the problems. Now I need help on one geometry problem:
Find the largest real number x for which there exists a real number y such that x^2 + y^2 = 2x + 2y.
1. Let A(t) = 3- 2t^2 + 4^t. Find A(2) - A(1).
2. Let
f(x)= (3x-7)/(x+1)
Find the domain of f. Give your answer as an interval.
3.The function f(x) satisfies
f(sqrt(x+1))=1/x
for all x>= -1, x is non zero. Find f(2)
Thanks, I figured out how to solve some of the problems.
For Problem one, my equation was: y= a(x-2)^2 + 1
I only need help on Q4,5,and 6
1. The grid lines in the graph below are one unit apart. The red parabola shown is the graph of the equation y = ax^2 + bx + c. Find a+b+c.

2. Find the vertex of the graph of the equation x -y^2 + 6y =8.
3. Find the area of the region enclosed by the graph of the equation x^2 + y^2 = 4x + 6y+13.
4. The graph of the equation y =ax^2 + bx + c, where a, b, and c are constants, is a parabola with axis of symmetry x = -3. Find b/a.
5. The grid lines in the graph are one unit apart. The red parabola shown is the graph of the equation y=ax^2 + bx + c. Find a*b*c.

6. The graph of (x-3)^2 + (y-5)^2=16 is reflected over the line y=2. The new graph is the graph of the equation x^2 + Bx + y^2 + Dy + F = 0 for some constants B, D, and F. Find B+D+F.
7. The point (a,b) is 5 units away from the point (6,3), and (a,b) lies on the line 5x - 4y = -14. What is the largest possible value of a?
I know it's a lot of problems so I'll be patient and wait as long as needed for help! Thx in advance guys!
Thanks guys, I got the solution to the problems!
Hey, I would like some help on this geometry problem, the full answer is fine as long as theres an explanation too!
Two lines l and m intersect at O at an angle of 28^\circ. Let A be a point inside the acute angle formed by l and m. Let B and C be the reflections of A in lines l and m, respectively. Find the number of degrees in \angle BAC.
Also, I am stuck on this algebra problem:
p and q are the solutions to the quadratic equation x^2 + 4x + 6 = 0.
p^2 and q^2 are the solutions to the quadratic equation x^2 + bx + c = 0.
Find b + c.
Thanks in advance!
