Explore our Trigonometry Calculators to solve all your trigonometric problems with ease. Instantly calculate trigonometric and inverse trigonometric functions, generate accurate graphs, and view complete ratio tables for sine, cosine, tangent, and more.
Triangle Theorems — AAA, AAS, ASA, ASS, SAS, SSS
Use these calculators to find unknown sides and angles of any triangle using well-known theorems: AAA, AAS, ASA, ASS, SAS, and SSS.
Get instant results for:
- Area (K)
- Perimeter (P)
- Semi-perimeter (s)
- Inradius (r) — radius of the inscribed circle
- Circumradius (R) — radius of the circumscribed circle
Easily solve for missing sides or angles using the Law of Cosines. Ideal for non-right triangles where you know two sides and the included angle, or all three sides.
Apply the Law of Sines to calculate unknown angles or sides in a triangle when you have at least one side-angle pair. Quick, accurate, and suitable for all triangle types.
Enter real numbers in degrees or radians to calculate the six primary trigonometric functions:
- Sine (sin)
- Cosine (cos)
- Tangent (tan)
- Cotangent (cot)
- Secant (sec)
- Cosecant (csc)
Trigonometric Function Graphs ƒ(x)
View detailed graphs of all six trigonometric functions over an x-axis range from -7 to 7. Perfect for understanding periodicity, amplitude, and phase shifts.
Compute trigonometric values for multiples or fractions of π radians. Enter numbers in π form to find results for all six functions — sin, cos, tan, cot, sec, and csc.
Graphs of Trigonometric Functions ƒ(π)
Visualize all six trigonometric functions across a scale from -2π to 2π. Interactive and precise, helping you see function behavior in terms of π.
Inverse Trigonometric Functions
Find accurate inverse trigonometric values (in degrees or radians) for:
- Arcsine (sin⁻¹)
- Arccosine (cos⁻¹)
- Arctangent (tan⁻¹)
- Arccotangent (cot⁻¹)
- Arcsecant (sec⁻¹)
- Arccosecant (csc⁻¹)
Graphs of Inverse Trigonometric Functions
Explore visual graphs for all six inverse trigonometric functions, showing their principal value ranges for clear understanding of each curve.
Understand trigonometric functions as ratios of triangle sides:
- Sine = Opposite / Hypotenuse
- Cosine = Adjacent / Hypotenuse
- Tangent = Opposite / Adjacent
Also explore cotangent, secant, and cosecant in relation to these side ratios.
