# Skyder i GeoGebra

Jakob Sloth Csikos shared this question 3 years ago

Hej GeoGebra,

Jeg er igang med et eksamensprojekt, og kan ikke få mit punkt til at følge den fulde linje. Så hvordan kan jeg oprette en skyder i GeoGebra, hvor et punkt - som hedder H - følger en eller flere skydere, i en cirkelbue. For at forstå det, har jeg vedhæftet et billede af det. Mit punkt H, skal altså følge den cirkelbue (den linje der er fuld).

Kan I hjælpe mig?

Mvh

Here is the GGB-file

Maybe this?

It's in the right direction.

But the parabel and the maximum is not correct.

I mean, the maximum of the parabel should be in A=(53,0678;1.8196) and the parabel should hit the x-axis in point B=(0;1.2)

Can you help me?

Now c is the exact copy from your file "SOP riffel.ggb".

Note: this is a circle and not a parable.

New:

• 2 variants (F and G, I think you need G)
• calculated maximum MaxY

I don't get it.

How can I use this?

This version is as simple as possible.

Note: P_1 I learn from you, very nice (more easy then with "ConjugateDiameter()").

But...

I translate "SOP riffel" to german ("schweres (Jagd)-Gewehr")

Now I think you need something like this.

Here the slider is the time and the curve is a parable.

Translate:

• Abschusswinkel = launch angle
• Abschussgeschwindigkeit = launch speed
• Weite = vastness
• Zeit = t = time
