This trigonometry calculator lets you calculate the trigonometric angle functions (sin, cos, tan, sec, csc, tan) in either degrees or radians. Not only this but the sohcahtoa calculator with steps will apply this particular mnemonics to determine the trigonometric angle ratios accurately, thereby representing the graph as well.
You can determine any trig function ratios by using this online six trigonometric functions calculator.
Input:
Output: Our trig ratio calculator does the following calculations:
Apart from angles only, you can also determine the sides of the right triangle by using another law of sines calculator.
The study of three angles of the triangle is called trigonometry. Our free trig calculator triangle also goes for determining all the interconnected angle ratios in a couple of moments. The following are the standard trigonometric function ratios that can also be computed for any angle by using our online find trigonometric ratios calculator:
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.
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
The ratio of perpendicular and base of the triangle is known as the tangent function.
Formula:
Tangent = Perpendicular/Base
Secant is exactly opposite of sine. In other words, it corresponds to the ratio of hypotenuse and perpendicular.
Formula:
Secant = Hypotenuse/Perpendicular
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
The ratio of base to the perpendicular of a triangle is known as cotangent function.
Formula:
Cotangent = Base/Perpendicular
Below are the formulas of all the inverse trigonometric functions:
It is the inverse of sine function.
Formula:
Arcsin = sin^{-1}x
The inverse of the cosine function is termed as arccos.
Formula:
Arccos = cos^{-1}x
The exact opposite of the tangent function is known as the arctan function.
Formula:
Arctan = tan^{-1}x
The reciprocal of cotangent function is called arccotangent function.
Formula:
Arccot = cot^{-1}x
This particular function is actually the inverse of the secant function.
Formula:
Arcsec = sec^{-1}x
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 azimuthally. 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.
