Prove that the polar equation of a planet's elliptical orbit is $$ r=\frac{\left(1-e^{2}\right) a}{1-e \cos \theta} $$ where \(e\) is the eccentricity and \(2 a\) is the length of the major axis.
The towers of a suspension bridge are 800 feet apart and rise 160 feet above the road. The cable between the towers has the shape of a parabola and the cable just touches the sides of the road midway between the towers. What is the height of the cable 100 feet from a tower?
The equation \(3 x^{2}-2 \sqrt{3} x y+y^{2}+2 x+2 \sqrt{3} y=0\) is in a he form \(A x^{2}+B x y+C y^{2}+D x+E y+F=0 .\) Use the equation to determine the value of \(B^{2}-4 A C\)
Write a polar equation of the conic that is named and described. Ellipse: a focus at the pole; vertex: \((4,0) ; e=\frac{1}{2}\)
Verify the identity: $$ \frac{\sec x}{\cot x+\tan x}=\sin x $$
