- The first artificial satellite to orbit the earth was Sputnik I. Its highest point above earth's surface was 947 km, and its lowest point was 228 km. The center of the earth was at one focus of the elliptical orbit. The radius of the earth is 6378 km. Find the eccentricity ofthe orbit.arrow_forwardGiven the equation of a conic in the form 8x^2 -12xy +17y^2 -20=0 we can convert this into standard form in the XY coordinate system without the XY term. After finding out what cot(2θ) is, we can use this information to find what sin θ and cos θ is by using the trigonometric identities 2sin^2θ=1-cos2θ and 2cos^2θ=1 +cos 2θ. So, what is the value of sin θ and cos θ?arrow_forwardFind the Orthogonal Trajectory of the Family of Centra Conics with common foci and axis.arrow_forward
- What kind of conics equation is thisarrow_forwardThe moon orbits Earth in an elliptical path with the center of Earth at one focus, as shown. The major and minor axes of the orbit have lengths of 768,800 kilometers and 767,641 kilometers, respectively. Find the greatest and least distances (the apogee and perigee) from Earth’s center to the moon’s center.arrow_forwardWrite a step-by-step procedure on how to classify conic sections given their equation in general conic formarrow_forward
- Analyze each conic.arrow_forwardIf all conics are defined in terms of a fixed point and a fixed line, how can you tell one kind of conic from another?arrow_forwardDetermine which conic is the one whose general equation has only one term raised to the square, that is, there’s either one x2 term or one y2 term, but not both.arrow_forward
