+
+The parabelfunc.py is used to calculate a ballistical curve with parameters for angle, speed, gravity to create a realistic flight.
+It returns its coordinates depending on the resolution (xmax-xmin) * (ymax-ymin). So you probably want to keep xmin and ymin at 0.
+0/0 is in mathematical representation left/down corner.
+
+The function is called 
+```
+berechneflugbahn(cow, xmin, xmax, ymin, ymax, startwinkel, startgeschwindigkeit, starthoehe)
+```
+
+and returns a list of x and y coordinates: [x1,y1,x2,y2....] like the following example for a display with a width of 10 points/pixel/char/weltraumgnietschies starting with x=0 
+```
+[0, 0, 1, 1.1, 2, 1.7, 3, 2.4, 4, 2.9, 5, 3.5, 6, 4.0, 7, 4.5, 8, 5.0, 9, 5.4]
+```
+
+The parameter cow is not useless, it can be set to any singlebyte ASCII string like "*" or some doublespaced UTF8 char like "🐄". If it is a singlechar in ASCII, which is the default, the curve will be calculated with singlesteps, if ist is a UTF8-String, each step will be 2 points, because we now know, we have a textmode display and doublewidth chars.
+
+```
+ # X-Resolution of the display 
+
+ cow="🐫"
+ xmax = 100
+ ymax = 40
+ ymin = 0
+ xmin = 0
+ startwinkel = 34
+ startgeschwindigkeit = 31
+ starthoehe = 0
+
+ergebnis = berechneflugbahn(cow, xmin, xmax, ymin, ymax, startwinkel, startgeschwindigkeit, starthoehe)
+
+for count in range(xmin, len(ergebnis), 2):
+    x, y = ergebnis[count], ergebnis[count + 1]
+    curpos(x, y)
+    print(cow, end="")
