MATH TERMS THAT START WITH T

Tangent :

In geometry a tangent or tangent line to a plane curve at a given point is the straight line that touches the curve at that point.

Trigonometry :

This word  is derived from two Greek words "trigon" and "metra". This is providing the relationship between the measurements and sides of the angle in a triangle.

Trigonometric Ratios :

We have six trigonometric ratios. They are sin θ,cos θ,tan θ,cosec θ, sec θ and cot θ

Trigonometric Ratios :

sin θ  =  Opposite side/Hypotenuse side

cos θ  =  Adjacent side/Hypotenuse side

tan θ  =  Opposite side/Adjacent side

Cosec θ  =  Hypotenuse side/Opposite side

Sec θ  =  Hypotenuse side/Adjacent side

cot θ  =  Adjacent side /Opposite side

Trigonometric Identities :

sin²θ  + cos²θ  =  1

sin²θ  =  1 - cos²θ

cos²θ  =  1 - sin²θ

sec²θ - tan²θ  =  1

sec²θ  =  1 + tan²θ

tan²θ  =  sec²θ - 1

csc²θ - cot²θ  =  1

csc²θ  =  1 + cot²θ

cot²θ  =  csc²θ - 1

Tangram :

A dissection Chinese puzzle consisting of seven flat shapes(tans) which are put together to form a shape.

Transverse :

It is a line that passes through two or more other lines that in the same plane at different points.

Two circles Intersecting Externally :

We can say two circles touch each other externally when they lie on the opposite sides of the common tangent. 

Tree Diagram :

One of the ways to find the prime factorization of a number is to use a visual representation called factor tree. As we add more branches, we will see that this visual representation looks like an upside down tree.

Let us find the prime factorization of 36 using factor tree as shown below.

Prime factorization of 36 :

36  =  2 x 2 x 3 x 3

Two Circles Intersecting Internally :

Two circles will be touch each other internally when they lie on the same side of the common tangent. 

Theorem :

A conjecture if it is proved becomes a theorem. Thus a statement which has been proved to be true is called theorems. A conjecture, if it is disproved becomes a false statement.

Total Surface Area :

Total Surface area is the second branch of the main topic area. Which means the measurement of extension of outer part of the solid completely. Whereas the curved surface-area is the measurement of extension of only the curved part of the solid. 

Tabulation of Data :

Tabulation of data is the method of systematic placing of data into tabular form. As we know, each table contains rows and columns, we can arrange the data in the symmetric form tabular form according to the collected information in rows and columns. The main purpose of this form is to simplify the presentation and facilitate the comparison.

Types of tabulation of data:

• Simple or one way tabulating data
• Double or two way tabulating data
• Complex tabulating
