Did Nasir Al Din Al-Tusi create trigonometry?
In astronomy, al-Tusi created very accurate tables of planetary motion, an updated planetary model, and critiques of Ptolemaic astronomy. He also made strides in logic, mathematics but especially trigonometry, biology, and chemistry. Nasir al-Din al-Tusi left behind a great legacy as well.

Nasir al-Din al-Tusi/Years of Living
Naṣīr al-Dīn al-Ṭūsī, in full Muḥammad ibn Muḥammad ibn al-Ḥasan al-Ṭūsī, (born Feb. 18, 1201, Ṭūs, Khorāsān [now Iran]—died June 26, 1274, Baghdad, Iraq), outstanding Persian philosopher, scientist, and mathematician.
Why is the Tusi couple important?
The Tusi couple is considered by historians of astronomy a key element of the Copernican heliocentric system. Historians showed that Persian astronomers of the 13th century from the Maragha school in southern Azerbaijan came very close to the discovery of the heliocentric Copernicus planetary system.
Which of Tusi’s ideas about evolution were correct?
Tusi explained that hereditary variability was the leading force of evolution. Tusi was right when he suggested: “The bodies are changing as a result of the internal and external interactions” – that is, as a result of environmental influences.
Who created trigonometry?
Hipparchus
Trigonometry in the modern sense began with the Greeks. Hipparchus (c. 190–120 bce) was the first to construct a table of values for a trigonometric function.
When was the Tusi couple created?
The Tusi couple was first introduced in the 13th century by Nasir al-Din al-Tusi (1201–1274) (a Persian polymath: architect, astronomer, mathematician, philosopher, physician, scientist, theologian) in his Tahrir al-Majisti = Commentary on the Almagest (1247) as a model for the latitudinal motion of the inferior …
What are six trigonometric functions?
There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).
Did Copernicus invent the Tusi couple independently?
Historians have considered the possibility that Copernicus might have invented the Tusi couple independently of al-Tūsī, but that doesn’t seem too likely, especially since Copernicus uses the same lettering labels as al-Tūsī, which are not the letters that a Western astronomer would normally use.
How hard is trigonometry?
Trigonometry is hard because it deliberately makes difficult what is at heart easy. We know trig is about right triangles, and right triangles are about the Pythagorean Theorem. About the simplest math we can write is When this is the Pythagorean Theorem, we’re referring to a right isosceles triangle.
