What is sum math?

A mathematical sum or maths sum is the result of adding two or more numbers together. It is the total of the numbers added together. For example, the sum of 3 and 7 is 10.

What is cos and sin?

Sine and cosine — a.k.a., sin(θ) and cos(θ) — are functions revealing the shape of a right triangle. Looking out from a vertex with angle θ, sin(θ) is the ratio of the opposite side to the hypotenuse , while cos(θ) is the ratio of the adjacent side to the hypotenuse .

What is Sinx equal to?

We can say that sin x = sin(x + 360◦). We say the function is periodic, with periodicity 360◦. Sometimes we will want to work in radians instead of degrees. If we have sin x in radians, it is usually very different from sin x in degrees.

How do you write cosecant?

Cosecant is one of the main six trigonometric functions and is abbreviated as csc x or cosec x, where x is the angle. In a right-angled triangle, cosecant is equal to the ratio of the hypotenuse and perpendicular. Since it is the reciprocal of sine, we write it as csc x = 1 / sin x.

Why is cosine called cosine?

The word sine (Latin sinus) comes from a Latin mistranslation by Robert of Chester of the Arabic jiba, itself a transliteration of the Sanskrit word for half of a chord, jya-ardha. The word cosine derives from a contraction of the medieval Latin complementi sinus.

Why is it called tangent?

The word tangent comes from Latin tangens meaning “touching”, since the line touches the circle of unit radius, whereas secant stems from Latin secans—”cutting”—since the line cuts the circle.

Who invented sine function?

Sine was introduced Aryabhata in India (476-550). From India it penetrated to the Muslim world, where several astronomers developed trigonometry further, one notable figure was Abu al Wafa (940-998), who composed sine tables. He also introduced tangent.
