I then put tape on the white surface (the inside) to hold the petals into the spherical shape. Since it has been so successful now I’ll make possible to English speakers to learn the technique, one of many of course. I also tried a slightly different method than Doctor Rick’s, making the width not that of the tangent line but of an arc of the sphere itself, for comparison (on the theory that stretching might give better results, and because that was Jessica’s own suggestion): Doing my own calculations, and making the width of a gore as (according to your question) a fraction of the circumference of the sphere, I get the equation of the curve on each side of it as, where x is the distance from the center, R is the radius of the sphere, and N is the number of gores. y = R (pi/N) cos (x/R) where x is the distance from the center, R is the radius of the sphere, and N is the number of gores.

Something Circle to Trace. Here is the result. Here are the side cross-section Doctor Rick referred to, and the top view parallel to the equator (through a line of latitude): E is a point on the equator, N and S are the poles, and P is a point on the circle at latitude L. Here I have added one gore to the picture, showing how its width is calculated, and how it wraps around to the poles: These gores are designed to lie outside the sphere, so that with a little wrinkling they could be pressed down onto the sphere; if the material were stretchable, you could make the sides, rather than the midline, of each gore lie on the sphere, and stretch the inside onto the sphere. You don’t want to ruin your job isn’t it? This is a good example of a case where the math can be done precisely, but it doesn’t matter in real life!
