Why is René Descartes considered the father of analytical geometry?

Because René Descartes developed the Cartesian coordinate system, this system allows geometric shapes to be expressed in algebraic equations.

Descartes' works is still today the basis in analytic geometry.

What is the difference between an Euler circuit and an Euler path?

The difference between an Euler circuit and an Euler path is in the execution of the process. The Euler path will begin and end at varied vertices while the Euler circuit uses all the edges of the graph at once.

Rene Descartes used reason with certainty to disprove God's existence?

In Discourse on Method it would seem that he indeed does disprove God's existence only to hastily come up with an excuse as to how, despite all the evidence previously provided, that God actually exists. The logical leap to get there as you might find isn't terribly convincing, but convincing enough for the clergy at the time as he was never reprimanded for the work. If you doubt that he disproved God, consider his epitaph: "He who hides well lives well." For someone using reason to disproves God's existence in the time that he lived, this seems especially apt.

Different types of lines and their meanings in math?

There are many types of lines used in math and some of them are:-

Parallel lines never intersect

Perpendicular lines meet at right angles

Lines of intersection have opposite equal angles

Solidus line separates the numerator from the denominator in fractions

Line of best fit used in data correlation

Number line has numbers from minus to positive in ascending order

Line segments have defined end points

Straight line equations are plotted on the Cartesian plane

Transversal line cuts through parallel lines with special angular properties

What is the principle of lactometer?

A Lactometer is a little glass instrument that tests the purity of milk based on density/buoyancy and works on the principle of the specific gravity of milk.

What is the answer to 23x16?

23

x16

138

230

368

This was direct multiplication

We can also Law of Distributivity

23 x 16

23 x(10+6)

230+138

368

Thus 368 is the required answer.

What was Alan turings profession?

Alan Turing was trained as a mathematician. During World War II, he worked for British Intelligence at Bletchley Park, where he specialized in cryptography (breaking secret codes). Using his expertise in mathematical logic, he developed an algorithm (a mathematical template) that was used to program a calculating machine to analyze German codes. The programming was successful and enabled the British to crack the German "Enigma" code; for several months the Allies had full access to German messages. Turing's work at Bletchley Park led directly to the development of the computer and modern research in artificial intelligence.

Although Turing never claimed to be a philosopher, his work on the nature of intelligence and machine "thinking" is considered a substantial contribution to the philosophical discussion on these issues.

How did Rene Descartes impact the Age of Enlightenment?

Rene Descartes made a huge impact on the Age of Enlightenment. He promoted theories on philosophy, mathematics, and science based on ideas that he got while dreaming.

Where is the tomb of Aristotle?
