Answer 1

Answer:

Trigonometry

Step-by-step explanation:

Trigonometry is a branch of mathematics which deals with relations between side length and angles of triangle.

There are some trigonometry relations

• Sin theta = p/h
• Cos theta = b/h
• tan theta = °p/b
• cosec theta = h/p
• sec theta = h/b
• cot theta = b/p

There Are Some Formulas

1 - sin^2 theta = cos^2 theta

1 + tan^2 theta =cot^2 theta

1 - cos^2 theta = sin^2 theta

1 + cot^2 theta = tan^2 theta

Answer 2

Answer:

The word Trigonometry is derived from the Greek word trigōnon, tri for triangle and metron for measure. Trigonometry is therefore the branch of mathematics which deals with the measurement of angles in triangles and focuses on the functions, application and calculations of angles.

There are six functions of an angle commonly used in trigonometry. They are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).
