Basic constant equation
sin²θ + cos²θ = 1 tan θ = sin θ / cos θ
1 + tan²θ = sec²θ 1 + cot²θ = csc²θ
And difference formula
sin(A±B) = sinA·cosB ± cosA·sinB cos(A±B) = cosA·cosB ∓ sinA·sinB
Multipoint Formula
sin 2θ = 2 sin θ cos θ cos 2θ = cos²θ - sin²θ = 2cos²θ - 1
Half-angle Formula
sin(θ/2) = ±√[(1-cosθ)/2] cos(θ/2) = ±√[(1+cosθ)/2]

Triangular function calculator: a mandatory tool for mathematics learning and engineering

Triangular functions are the core elements of the study of triangles in mathematics and are widely used in the fields of physics, engineering, astronomy and navigation. This online tool provides not only the underlying sine (sin), cosine (cos), tangent (tan) The calculations also bring together complex triangles for solving and unit circle dynamic demonstrations, which are ideal assistants for learning and working.

What's a trigonometry?

Triangular functions are functions that describe the ratio of angles to edges in a straight-angled triangle. In a unit circle (a circle with a radius of 1), angle thorium , the cosine corresponds to the x-coordinate. Through ours. Unit Circle Dynamics Demonstration , you can observe intuitively how the function values fluctuate between [1, 1] with the angle.

How do you solve a triangle?

We can use the triangulated portion of information (e.g., triangulation SSS) if known Cosine Theorem To solve the unknown angle. The cosine theorem formula is: c² = a² + b² - 2ab·cos(C) 。 Our triangle solver supports input of any triangulation, auto-validing triangle variations and calculating all inner angles, area (Helen formula) and outer circle radiuss.

Overview of core functions

  • Scientific function calculation: Supports six basic trigonometric functions (sin, cos, tan, csc, sec, cot), supports angles and radians freely switching.
  • Inverse query: Quick get the arcsin, arccos, anrctan corresponding angle values.
  • Interactive circle: Drag or enter a number, observe in real time the projection changes on the axis, and understand the definition of functions.
  • Constant equation reference: The usual multi-angle and differential formulas are built into them to facilitate quick access by students and scientists.
