I have seen the post on the rotation of arrows and one of the post is mine. However, I don't understand how to do accomplish it myself. For instance, I am making a picture of Hohmann transfer where on the orbits I want triangular arrows pointing counter clockwise and "v" type arrow on the transfer.
This part is completed:
My goals is to put on the outer orbit 2 of the triangle arrows: one at 30 degrees and the other at 210 degrees.
The inner orbit 2 triangular arrows at 135 and 315 degrees.
For the Hohmann transfer I want to put 2 arrows: one about 40 percent of the curve and the other 70 percent. However, I also am not sure how to create an arc that goes between the two orbits and arrives at (-3,0). I tried the arc command but that was just guessing and it wasn't looking pretty.
For some reason, only one arrow shows up on the Hohmann transfer. I specified at 0.15 and 0.35.
