Summary :The cos trigonometric role calculates the cosine the an edge in radians, levels or gradians.

You are watching: Cos^2(pi/3)

cos online

description :Cosine functionThe calculator permits to use many of the trigonometric functions, that is possible to calculation the cosine, the sine and also the tangent of an angle with the functions of the exact same name..

The trigonometric function cosine noted cos, permits to calculate the cosine of an angle online , that is possible to use various angular systems : degrees, gradians and radians wich is the angular unit by default.

## Calculation that the cosine

### Cosine calculating an angle in radians

The cosine calculator allows through the cos function to calculate online the cosine that an edge in radians, girlfriend must first select the desired unit by clicking the choices button calculate module. After that, you have the right to start your calculations.

To calculate cosine online of `pi/6`, enter cos(`pi/6`), after calculation, the result `sqrt(3)/2` is returned.

note that the cosine duty is may be to recognize some one-of-a-kind angles and also make the calculations v special linked values in exact form.

### Calculate the cosine the an edge in degrees

To calculate the cosine of an angle in degrees, friend must very first select the wanted unit by clicking the choices button calculate module. ~ that, you can start her calculus.

To calculate cosine of 90, go into cos(90), after calculation, the restults 0 is returned.

### Calculate the cosine the an angle in gradians

To calculation the cosine the an angle in gradians, you must very first select the preferred unit by clicking on the alternatives button calculation module. After that, you have the right to start your calculus.

To calculation cosine the 50, get in cos(50), after computation, the result `sqrt(2)/2` is returned.

keep in mind that the cosine role is may be to recognize some special angles and do the calculus with special associated exact values.

## Special cosine values

The cosine admits some unique values i m sorry the calculator is able to determine in exact forms. Right here is the list of the special cosine values:

 cos(`2*pi`) `1` cos(`pi`) `-1` cos(`pi/2`) `0` cos(`pi/4`) `sqrt(2)/2` cos(`pi/3`) `1/2` cos(`pi/6`) `sqrt(3)/2` cos(`2*pi/3`) `-1/2` cos(`3*pi/4`) `-sqrt(2)/2` cos(`5*pi/6`) `-sqrt(3)/2` cos(`0`) `1` cos(`-2*pi`) `1` cos(`-pi`) `-1` cos(`pi/2`) `0` cos(`-pi/4`) `sqrt(2)/2` cos(`-pi/3`) `1/2` cos(`-pi/6`) `sqrt(3)/2` cos(`-2*pi/3`) `-1/2` cos(`-3*pi/4`) `-sqrt(2)/2` cos(`-5*pi/6`) `-sqrt(3)/2`

## Main properties

`AA x in RR, k in ZZ`, `cos(-x)= cos(x)` `cos(x+2*k*pi)=cos(x)` `cos(pi-x)=-cos(x)` `cos(pi+x)=-cos(x)` `cos(pi/2-x)=sin(x)` `cos(pi/2+x)=-sin(x)`

## Derivative that cosine

The derivative the the cosine is equal to -sin(x).

## Antiderivative of cosine

The antiderivative that the cosine is same to sin(x).

## Properties of the cosine function

The cosine duty is an also function, for every actual x, `cos(-x)=cos(x)`. The repercussion for the curve representative the the cosine duty is that it admits the axis of the ordinates as axis the symmetry.

## Equation v cosine

The calculator has actually a solver which enables it to solve equation v cosine the the type cos(x)=a. The calculations to achieve the result are detailed, therefore it will certainly be possible to fix equations favor `cos(x)=1/2` or `2*cos(x)=sqrt(2)` through the calculation steps.

The cos trigonometric role calculates the cosine that an edge in radians, levels or gradians. Syntax :

cos(x), where x is the measure of an angle in degrees, radians, or gradians.

examples :

cos(`0`), return 1

Derivative cosine :

To differentiate duty cosine online, it is possible to use the derivative calculator which enables the calculate of the derivative of the cosine function

The derivative that cos(x) is derivative(`cos(x)`)=`-sin(x)`

Antiderivative cosine :

Antiderivative calculator enables to calculation an antiderivative of cosine function.

An antiderivative the cos(x) is antiderivative(`cos(x)`)=`sin(x)`

limit cosine :

The limit calculator enables the calculation of borders of the cosine function.

Inverse function cosine :

The inverse function of cosine is the arccosine function noted arccos.

graphics cosine :

The graphing calculator is able come plot cosine role in its meaning interval.

property of the function cosine : The cosine duty is an even function. calculate online with cos (cosine)
