This gives your current location, from which you can navigate to your destination.

### Arab and their contribution in trigonometry?

The Arabs invented the modern math of trigonometry. They used Ancient Greek proofs (such as those made by Pythagoras and Demosthenes) to discover that the relationships between the lengths of sides of a right angle triangle were consistent when the angles were consistent. They proved methods to derive the proper value relationships, resulting in the trigonometry tables that have now been plugged into in every scientific calculator.
