## TrigCalc - A Fully Functional Step By Step Triangle Calculator

TrigCalc is a very comprehensive, step by step, trigonometry calculator created for but not limited to trigonometry students seeking extra help or understanding of the subject. At the moment we have launched different calculators for math problems.

## 90 Degree triangle Calculator

Everything in trigonometry seems to revolve around the 90 degree triangle and its ratios. A 90 degree triangle is defined as a triangle with a right angle or in other words a ninety degree angle. Given any known side length of a 90 degree triangle and one other value (another side, angle, area value, etc), one can find all unknown values of the same 90 degree triangle.

## Right Triangle Calculator

Right triangle calculator exemplifies this truth by taking in two values (one side and any other value) and returning all missing values in exact value and decimal form while displaying the formulas and calculation process for each of the missing values. The right triangle calculator is simple and easy to use for students, teachers, and anyone needing help with their math. Try it out!

## Oblique Triangle Calculator

An oblique triangle is defined as a triangle without a right angle or ninty degree angle. Given three known values of an oblique triangle with one of those values being a side length, all other unknown values of the same triangle can be calculated. Oblique triangles use a set of formulas unique from right triangles and these formulas can be displayed on the oblique triangle calculator page of our website. An oblique triangle calculator takes in one side length and any two other values and returns the missing values in exact value and decimal form in addition to the step-by-step calculation process for each of those missing values.

## Circle Calculator

A circle is defined as a round figure whose boundary consists of points each equidistant from the center point. Circles consist of four segments, the radius, diameter, circumference, and area. If just one of these values is known, all of the other values can be calculated. In a circle calculator, you can do just that. This takes in any one known value of the circle and returns all missing values in exact value and decimal form as well as the step-by-step calculation process for each one of those values.

## Sector Calculator

A sector is defined as the area between two radiuses and the connecting arc of a circle. The five major parts of a sector are the angle, radius, chord, arc, and area. Given either an angle measure or radius length and any other value (two in total), all other values of the sector can be calculated. In the sector calculator, you can enter two values (at least one being an angle or radius) and receive all unknown values in exact value and decimal form and the step-by-step process for each missing value.

## Identity Calculator

For a list of trigonometric identities, the identity reference page displays all of them. If seeking to calculate identities, TrigCalc includes identity calculators for 6 of the trigonometric identities including sum difference, double angle, half angle, power reduction, sum to a product, and product to sum. In each of the identity calculators, given any function value and quadrant of theta, the exact value and calculation process will be displayed. Decimal approximations for each of the trigonometric identities can be calculated as well.

## Coterminal Angle Calculator

Coterminal angles are angles sharing the same terminal and initial sides. Calculating coterminal angles involves adding or subtracting multiples of 360 degrees. Coterminal angle calculator allows you to find either the least positive or negative values coterminal with a given angle in degree or radian form. This calculator also returns exact values, decimal approximations, and the step-by-step calculation process of the angle.

## Supplementary Angles Calculator

Supplementary angles are angles whose sum equals 180 degrees. In the supplementary angle calculator, the supplement of any degree or radian value will be calculated and displayed alongside the calculation process and decimal approximation.

## Complementary Angle Calculator

Complementary angles are angles whose sum equals ninety degrees. In a complementary angle calculator, the supplement of any degree or radian value will be calculated and displayed alongside the calculation process and decimal approximation. All calculators are very necessary math solvers as well as right triangle calculators.

## Double Angle Calculator

The double angle formula calculator is a great tool if you'd like to see the step by step solutions of the sine, cosine and tangent of double a given angle.
