Answer:

Coordinate geometry is one of the most important and exciting ideas of mathematics. In particular it is central to the mathematics students meet at school. It provides a connection between algebra and geometry through graphs of lines and curves. This enables geometric problems to be solved algebraically and provides geometric insights into algebra.

The invention of calculus was an extremely important development in mathematics that enabled mathematicians and physicists to model the real world in ways that was previously impossible. It brought together nearly all of algebra and geometry using the coordinate plane. The invention of calculus depended on the development of coordinate geometry.

What does h20 mean on the periodic elements chart
Paladinen [302]

Answer:

The compound, H₂O, will not be found on the periodic table. This is because the periodic table only consists of individual elements. That being said, the elements found within H₂O are located on the periodic table. H₂O consists of hydrogen, denoted by the symbol "H", and oxygen, denoted by the symbol "O". The subscript (the 2) tells us that there are 2 hydrogen atoms located in the H₂O molecule.

Hydrogen is the first element listed on the periodic table and can be found in the top leftmost position. Oxygen is the eighth element on the periodic able and is located in the second row at the top right.
