Find Area of Polar Curve: Cos(6ǿ)

Click For Summary
SUMMARY

The discussion centers on finding the length of one petal of the polar curve defined by the equation cos(6θ). It is established that the correct interval to use for calculating the length of one complete petal is from -π/12 to π/12. Using the interval from 0 to π/12 only captures half of the petal, necessitating either a doubling of the result or the use of the full interval for accurate measurement.

PREREQUISITES
  • Understanding of polar coordinates and curves
  • Knowledge of trigonometric functions, specifically cosine
  • Familiarity with calculus concepts related to arc length
  • Ability to manipulate and solve equations involving angles
NEXT STEPS
  • Learn how to calculate the arc length of polar curves
  • Study the properties of polar equations and their graphs
  • Explore the implications of symmetry in polar curves
  • Investigate the use of integration in finding lengths of curves
USEFUL FOR

Students and educators in mathematics, particularly those focusing on calculus and polar coordinates, as well as anyone interested in graphing and analyzing polar curves.

Hey guys,

I just wanted to know, if my polar curve is cos(6ǿ) and i have to find the length of one peddle... can i use the interval of 0 and Pi/12?

Thanks a lot!

One peddle? Oh! One "petal"! cosine goes from 0 to 0 between [itex]\pi/2[/itex] and [itex]\pi/2[/tex]. [itex]6\theta= \pi/2[/itex] when [itex]\theta= \pi/12[/itex].<br /> <br /> I would recommend using -[itex]\pi/12[/itex] to [itex]\pi/12[/itex]. 0 to [itex]\pi/12[/itex] will only give half of a petal. Of course, if you are really clever, you could use 0 to [itex]\pi/12[/itex] and then multiply by 2.[/itex]
