* by default Calci use Radian as angle

[[Manuals/calci/DTAN | DTAN]] can be used if the angle is in degrees.  

[[Manuals/calci/ACOS | ACOS]] can be used if the angle is in degrees.  

The angle can be a single value or any complex array of values.

The angle can be a single value or any complex array of values.

For example TAN(1..100) can give an array of the results, which is the TAN value for each of the elements in the array. The array could be of any shape.  

For example ACOS(1..100) can give an array of the results, which is the ACOS value for each of the elements in the array. The array could be of any shape.  

==Description==

==Description==

Consider &nbsp;&nbsp;&nbsp; '''x = 90'''&nbsp;&nbsp;&nbsp;  then &nbsp;&nbsp;&nbsp;  '''=TAN(RADIANS(90))'''&nbsp;&nbsp;&nbsp; gives &nbsp;&nbsp;&nbsp;'''1''' <br/>

Consider &nbsp;&nbsp;&nbsp; '''x = 90'''&nbsp;&nbsp;&nbsp;  then &nbsp;&nbsp;&nbsp;  '''=TAN(RADIANS(90))'''&nbsp;&nbsp;&nbsp; gives &nbsp;&nbsp;&nbsp;'''1''' <br/>

*This function gives the tangent of 'x'.

This function is the inverse function of cos in trignometry,and also it is called as cyclometric function.ACOS is described as arcCOS and denoted by cos-1 (x).In ACOS(X) ,x value should be with in -1&1.Here x is in radians. To convert a degree value to radian, multiply 'x' with PI()/180 or use the radians function RADIANS(X)

*In a right angled triangle, '''TAN = Opposite / Adjacent''' or '''SIN / COS'''.<br/>

*By default, Calci takes the angle in Radians.

*To convert Radian to Degree, multiply with 180/PI() or we have to use the Radians function like TAN(RADIANS(x))

The following example shows how TAN is applied to an array of numbers containing numbers 1..10.

The following example shows how ACOS is applied to an array of numbers containing numbers 1..10.
