There are 6 t-ratios ( trigonometric ratios) for right angle triangle are:
- Sine(sin)
- Cosecant(Cos)
- Tangent(Tan)
- Cosecant(Cos)
- Secant(Sec)
- Cotangent(Cot)
Trigonometry definition: It is that category of mathematics which deals with the measurement angles and the queries allied with angles.
Trigonometric Ratios
The ratios among separate sides of a right-angled triangle concerning its acute angles are called trigonometric ratios.
The different three sides of the right-angled triangle are:
- Perpendicular (opposite side to the angle)
- Hypotenuse (the longest side)
- Base (Adjacent side to the angle)
How to Find Trigonometric Ratios?
Let ∠ BAC = θ be an acute angle of a right angled Δ ABC.
In right-angled Δ ABC , let
AB = Base (B),
AC= Hypotenuse (H) and
BC = Perpendicular (P)
Trigonometric Ratios Table of Some Specific Angles
Here is the table of trigonometric ratios for some given angles such as 0 °, 30 °, 45 °, 60 °, and 90°, that is mostly used in mathematical calculations.
