Sin, Cos & Tan – Triangle Formulas You will need to understand sin, cos, and tan triangle formulas for your exam. Remember that the hypotenuse is the side of the triangle opposite the right angle. The adjacent side is next to the angle being measured. ...
Cosecant (cosec)-> cosecθ = 1/sinθ Secant (sec)-> secθ = 1/cosθ Cotangent (cot)-> cotθ = 1/tanθ Angle Sum and Difference Formulas: These formulas express the trigonometric functions of the sum or difference of two angles in terms of the trigonometric functions of the individual...
tan A = sin B = cos B = tan B = We hope that the free math worksheets have been helpful. We encourage parents and teachers to select the topics according to the needs of the child. For more difficult questions, the child may be encouraged to work out the problem on a piece of pap...

There are different formulas in trigonometry depicting the relationships between trigonometric ratios and the angles for different quadrants. The basic trigonometry formulas list is given below:1. Trigonometry Ratio Formulassin θ = Opposite Side/Hypotenuse cos θ = Adjacent Side/Hypotenuse tan θ = ...
The Trigonometric formulas or Identities are the equations which are true in the case of Right-Angled Triangles. Some of the special trigonometric identities are given below – Pythagorean Identities sin²θ + cos²θ = 1 tan2θ + 1 = sec2θ cot2θ + 1 = cosec2θ sin 2θ = 2 ...

Sum and Difference Formulas (和差公式) sin(α+β) = sinα cosβ + cosα sinβ sin(α-β) = sinα cosβ - cosα sinβ cos(α+β) = cosα cosβ - sinα sinβ cos(α-β) = cosα cosβ + sinα sinβ tan(α+β) = (tanα + tanβ)/(1 - tanα tanβ) ...
Trigonometry, the branch of mathematics concerned with specific functions of angles. There are six functions commonly used in trigonometry: sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). Learn more about trigo
What are the three formulas of trigonometry? In a right-angled triangle, if an angle, x, is specified: sin(x) is the ratio of the side opposite the angle and the hypotenuse, cos(x) is the ratio of the side adjacent to the angle and the hypotenuse, tan(x) is the ratio of si...
