Calculus - Integration: Double Integrals (9 of 9) Example 8: Finding Area: Polar Coordinates: r=cosx

In this video I will find A=? of 1 leaf of r=cosx.

Thank you for the excellent video once more Mr. Michel! I had a question: How did you know that the right end of the leaf was at r=1?

A difficult problem but you made it easy. PERFECT!!! Thanks.

when you calculate the arc length of small element you said it is equal to r d(theta), is the distance from the origin to the small element is r, the total radius ??

sir i don't get it why there is a 1/6 before the integral of cos 6 teta

Hello Professor,
Would you mind making a video about cycloids?

2:38 I don't quite get that, "you get half the area... so you need to write down 2 at the front of the integral", I thought that you don't have to multiply by 2 because it is an infinitesimal surface area dA

Hey, can you make more videos solving double integrals in Polar Coordinates?

didn't get how he came up to chose 30 degrees to evaluate the leaf

u britisher, join ana sir class at allen kota, u will get more of maths
