To write: The equation of the ellipse that is tangent to the x -axis and y -axis and has its center at

Answer to Problem 38E
Explanation of Solution
Given information: Tangent to the x -axis and y -axis and has its center at
Calculation:
Center at
Tangent to both axis means those are the endpoints. The distance from each is a and b respectively:
The distance from the center to the x -axis is larger. This tells us
y -term
This gives us finally:

- Explain the conditions under which the Radius of Convergence of the Power Series is a "finite positive real number" r>0arrow_forwardThis means that when the Radius of Convergence of the Power Series is a "finite positive real number" r>0, then every point x of the Power Series on (-r, r) will absolutely converge (x ∈ (-r, r)). Moreover, every point x on the Power Series (-∞, -r)U(r, +∞) will diverge (|x| >r). Please explain it.arrow_forwardExplain the conditions under which Radious of Convergence of Power Series is infinite. Explain what will happen?arrow_forward

- Consider the function f(x) = x²-1. (a) Find the instantaneous rate of change of f(x) at x=1 using the definition of the derivative. Show all your steps clearly. (b) Sketch the graph of f(x) around x = 1. Draw the secant line passing through the points on the graph where x 1 and x-> 1+h (for a small positive value of h, illustrate conceptually). Then, draw the tangent line to the graph at x=1. Explain how the slope of the tangent line relates to the value you found in part (a).
