is because the integral gives the wrong answer in poorly chosen coordinates. For example r0=2π r=R 1 dr d0 = 2πR, but we know this integral should be TR², the area of the unit disk.

true or false and why please

The reason we need different coordinate systems when calculating area integrals
Transcribed Image Text:The reason we need different coordinate systems when calculating area integrals
is because the integral gives the wrong answer in poorly chosen coordinates. For example
r0=2π r=R
1 dr d0 = 2πR,
but we know this integral should be TR², the area of the unit disk.
