The angles by which trigonometric functions can be represented are called as trigonometry angles. The important angles of trigonometry are 0°, 30°, 45°, 60°, 90°. These are the standard angles of trigonometric ratios, such as sin, cos, tan, sec, cosec, and cot. Each of these angles has different values with different trig functions • Trigonometry angles are the angles given by the ratios of the trigonometric functions. Trigonometry deals with the study of the relationship between angles and the sides of a triangle. The angle value ranges from 0-360 degrees. The important angles in trigonometry are 0°, 30°, 45°, 60°, 90°, 180°, 270° and 360°. And the important six trigonometric ratios or functions are sine, cosine, tangent, cosecant, secant and cotangent. • Angle (in Degrees) 0° 30° 45° 60° 90° 180° 270° 360° • Angle (in Radians) 0 π/6 π/4 π/3 π/2 π 3π/2 2π • Sin 0 1/2 1/√2 √3/2 1 0 -1 0 • Cos 1 √3/2 1/√2 1/2 0 -1 0 1 • Tan 0 1/√3 1 √3 ∞ 0 ∞ 0 • Cot ∞ √3 1 1/√3 0 ∞ 1 ∞ • Sec 1 2/√3 √2 2 ∞ -1 ∞ 1 • Cosec ∞ 2 √2 2/√3 1 ∞ -1 ∞ • Formulae:- • Supplementary angles ( = sum is π) • Sin ( π – α ) = sin α • Cos (π – α ) = – cos α • Tan (π – α ) = – tan α • Cot (π – α) = – cot α • Anti-supplementary Angles (= difference is π) • Sin ( π + α ) = – sin α • Cos (π + α ) = – cos α • Tan (π + α ) = tan α • Cot (π + α ) = cot α • Opposite Angles ( = sum is 2π) • Sin ( 2π – α ) = – sin α • Cos (2π – α ) = cos α • Tan (2π – α ) = -tan α • Cot (2π – α ) = – cot α • Complementary Angles (= sum is π/2) • Sin ( π/2 – α ) = cos α • Cos (π/2 – α ) = sin α • Tan (π/2 – α ) = cot α • Cot (π/2 – α ) = tan α • Keywords:- trigonometry class 10 | trigonometry | trigonometry table | class 10 trigonometry | trikonamiti math class 10 | trikonamiti | trigonometry table class 10 learn trick | trigonometry formulas | trikonmiti | dear sir trigonometry | class 10 maths trigonometry | trignometry | class 10th trigonometry | triginometry class 10 formulas | trigonometry tricks • #trigonometry #trigonometryttable #trigonometryclass10 #trikonamiti #math #tricks • #trigonometryformulas • Music:- Maestro Tlakaelel • Artist :- Jesse Gallagher • Fair Use Copyright Disclaimer:- This video is solely meant for educational purpose we do not want to hurt sentiments if any.
