The discussion revolves around calculating the area under a trochoid curve defined by parametric equations for the case where the distance d is less than the radius r. Participants are examining the integration process involved in this calculation.
The discussion is ongoing, with some participants seeking clarification on the original poster's intentions and the details of their calculations. There is a noted lack of explicit consensus on the approach being taken, and some guidance has been offered regarding the need for clearer problem statements.
There is an indication that the original poster may not have provided sufficient detail in their problem statement, which is affecting the ability of others to assist effectively.
nameVoid said:x=rT-dsinT
y=r-dcosT
trochoid for d<r
integrating this on 0,2pi = 4x[0,pi/2] I am getting 2r^2pi-8rd+d^2pi text is just showing 2r^2pi+d^2pi
