Stay focused!

What Is Trigonometry?

The study of three angles of the triangle is called trigonometry.

Pic…

Our free trig calculator triangle also goes for determining all the interconnected angle ratios in a couple of moments.

Trigonometric Ratios:

The following are the standard trigonometric function ratios that can also be computed for any angle by using our online find trigonometric ratios calculator:

Sine:

The ratio of perpendicular to the hypotenuse length is termed sine.

Formula:

Sine = Perpendicular/Hypotenuse

The exact value of the sine angles can be computed using this trigonometry calculator triangle.

Cosine:

In trigonometry, the ratio of the base to the hypotenuse of the triangle is known as the cosine function that could be understood in detail by a free cosine calculator.

Formula:

Cosine = Base/Hypotenuse

Tangent:

The ratio of perpendicular and base of the triangle is known as the tangent function.

Formula:

Tangent = Perpendicular/Base

Secant:

Secant is exactly opposite of sine. In other words, it corresponds to the ratio of hypotenuse and perpendicular.

Formula:

Secant = Hypotenuse/Perpendicular

Cosecant:

Like sine and secant, cosecant is the ratio opposite to that of the cosine. Simply put, the ratio of hypotenuse to the base of the triangle is known as the cosecant.

Formula:

Cosecant = Hypotenuse/Base

Cotangent:

The ratio of base to the perpendicular of a triangle is known as cotangent function.

Formula:

Cotangent = Base/Perpendicular

Inverse Trigonometric Functions:

Simply put, the inverse of trigonometric functions are inverse trigonometric functions. Among these include:

Arcsine:

It is the inverse of sine function.

Formula:

Arcsin = sin^{-1}x

Arccos:

The inverse of the cosine function is termed as arccos.

Formula:

Arccos = cos^{-1}x

Arctan:

The exact opposite of the tangent function is known as the arctan function.

Formula:

Arctan = tan^{-1}x

Arccotangent:

The reciprocal of cotangent function is called arccotangent function.

Formula:

Arccot = cot^{-1}x

Arcsecant:

This particular function is actually the inverse of secant function.

Formula:

Arcsec = sec^{-1}x

Arccosecant:

The inverse of cosecant function is arccosecant function.

Formula:

Arccosecant = cosec^{-1}x

All of these trig functions yield different degrees or radians values for different measures of azimuthals. And it is pretty hard to calculate for each value separately. But this is where our free right triangle trigonometry calculator comes to aid. So use this calculator and start solving for different angles.
