Who discovered the systems of linear equation?
The concept of systems of linear equations dates back to ancient civilizations such as Babylonians and Egyptians. However, the systematic study and formalization of solving systems of linear equations is attributed to the ancient Greek mathematician Euclid, who introduced the method of substitution and elimination in his work "Elements." Later mathematicians such as Gauss and Cramer made significant contributions to the theory and methods of solving systems of linear equations.
Who first accurately calculated the circumference of the Earth?
Eratothsenes Follow the link to his very cool projectThe Ancient Greeks - and they got it right, which was more than Columbus did!The Greek mathematician Eratosthenes calculated the circumference of the Earth fairly accurately over 2300 years ago!Eratosthenes was the first person to do this. He measured the distance netween two points and the different angles mad by the Sun - and worked out from these. His result was surprisingly accurate.
Where did the distance formula come from?
the ancient Egyptians
Inventors of algebra?
