Trigonometry Values

Trigonometry is a fascinating branch of mathematics that deals with the relationships between the angles and sides of triangles. Central to this are trigonometry formulas, which allow us to solve problems in engineering, physics, and even astronomy. These formulas, including sine, cosine, and tangent, help us understand and apply the properties of right triangles. By mastering trigonometry formulas, students and professionals can enhance their analytical skills and solve complex spatial problems. Overall, trigonometry values are not just theoretical; they have practical applications in various scientific and real-world contexts.

What are Trigonometry Values?

Trigonometry values refer to the ratios of the sides of a right triangle relative to one of its acute angles. These values are fundamental in trigonometry, a branch of mathematics that deals with the relationships between angles and sides of triangles.

Trigonometry Values Table

Let’s explore the trigonometric values for angles 0°, 30°, 45°, 60°, and 90°, covering the functions sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). We’ll use the context of a right triangle to understand how these values are calculated and their significance. This exploration will provide a practical understanding of how each trigonometric function relates to specific angles in a triangle, enhancing our grasp of fundamental trigonometric concepts. To assist with this, you can download a Trigonometry formula table that includes all these values for quick reference.

Consider the right-angled triangle ABC, where angle B is a right angle. In this triangle, the hypotenuse is AC. The side AB, adjacent to angle θ, is referred to as the adjacent side, while the side BC, opposite angle θ, is known as the perpendicular side

Trigonometry values are based on three major trigonometric ratios, Sine, Cosine, and Tangent.

  • sin θ = Perpendicular/Hypotenuse=BC/AC
  • cos θ = Base/Hypotenuse=AB/AC
  • tan θ = Perpendicular/Base=BC/AB

Similarly, we can define the reciprocal trigonometric properties for the ratios secant (sec), cosecant (csc), and cotangent (cot).

  • sec θ = Hypotenuse/Base=AC/AB
  • cosec θ = Hypotenuse/Perpendicular=AC/AB
  • cot θ = Base/Perpendicular=AB/BC
  • Sec θ . Cos θ =1
  • Cosec θ . Sin θ =1
  • Cot θ . Tan θ =1

Trigonometry Ratios Formula

  • Tan θ = sin θ/cos θ
  • Cot θ = cos θ/sin θ
  • Sin θ = 1/cosec θ
  • Cos θ = sin θ/tan θ = 1/sec θ
  • Sec θ = tan θ/sin θ = 1/cos θ
  • Cosec θ = 1/sin θ


  • Sin (90°-θ) = Cos θ
  • Cos (90°-θ) = Sin θ
  • Tan (90°-θ) = Cot θ
  • Cot (90°-θ) = Tan θ
  • Sec (90°-θ) = Cosec θ
  • Cosec (90°-θ) = Sec θ
