When I was using SolidWorks, I encountered an issue: when I used the "Equation Driven Curve" command, I selected the parametric equation option to draw a cardioid. The equation is as follows: 5*(1+cos(t))cos(t), 5(1+cos(t))*sin(t), with t ∈ (0, 2π). However, an error occurred, the sketch reported an error, and the graph I expected was not drawn. I have attached two images below to clearly illustrate the problem I encountered. I hope someone knows how to solve this issue. To get the solution as soon as possible, please contact me via my email: 3677610208@qq.com. Thank you very much!
