What is the equation for the given curve in polar coordinates?

Click For Summary
SUMMARY

The equation for the given curve in polar coordinates derived from the parametric equations x = e^k cos(k) and y = e^k sin(k) is r = e^k. This relationship holds for all values of K in the range -∞ < K < ∞. The transformation from Cartesian to polar coordinates is confirmed by the equation r^2 = e^(2k), leading to the conclusion that r = √(e^(2k)) = e^k. This provides a clear representation of the curve in polar form.

NEXT STEPS
  • Study the conversion of Cartesian coordinates to polar coordinates in detail.
  • Explore the properties of exponential functions and their graphs.
  • Learn about parametric equations and their applications in different coordinate systems.
  • Investigate the implications of polar equations in calculus, particularly in integration and area calculations.
USEFUL FOR

Homework Statement



x = eKcos(k)
y=eKsin(k)

-∞ < K < ∞

Find an equation in polar coordinates for the above curve


The Attempt at a Solution



I am not fully clear as to what the question is asking.

If its asking for (r,k), where K is normally a theta value then it would be (e^k,k)

other than that,

x^2+y^2=e^2k

r^2 = e^2k

r = √e^2k = e^k

---

Any help or suggestions would be appreciated!

r = ek is the answer you're looking for. It's an equation in polar coordinates and spans the same curve as your original parametric equations.
