Find the Properties 5x^2+3y^2=15

Problem

5*x2+3*y2=15

Solution

1. Standardize the equation by dividing both sides by 15 to set the right side equal to 1

(5*x2)/15+(3*y2)/15=15/15

2. Simplify the fractions to identify the standard form of an ellipse (x2)/(b2)+(y2)/(a2)=1

(x2)/3+(y2)/5=1

3. Identify the center (h,k) from the numerator terms (x−h)2 and (y−k)2

Center=(0,0)

4. Determine the semi-axes by taking the square roots of the denominators, where a2 is the larger value.

a2=5⇒a=√(,5)

b2=3⇒b=√(,3)

5. Identify the orientation of the major axis. Since a2 is under the y2 term, the ellipse is vertical.

Major Axis: Vertical

6. Calculate the focal distance c using the relationship c2=a2−b2

c2=5−3=2

c=√(,2)

7. Find the vertices by moving a units from the center along the major axis (ydirection).

Vertices=(0,±√(,5))

8. Find the foci by moving c units from the center along the major axis (ydirection).

Foci=(0,±√(,2))

9. Find the co-vertices by moving b units from the center along the minor axis (xdirection).

Co-vertices=(±√(,3),0)

10. Calculate the eccentricity e using the formula e=c/a

e=√(,2)/√(,5)=√(,10)/5

Final Answer

Center: *(0,0), Vertices: *(0,±√(,5)), Foci: *(0,±√(,2)), Eccentricity: √(,10)/5
