TAN(Number)

where Number is the angle in Radians
by default, Calci use angle in Radians.
- TAN(), returns the tangent of the given angle

DTAN can be used if the angle is in degrees.

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 values either '+' or '-' like 1..5@TAN or (-5)..(-1)@TAN.

Description

Consider x = 60 then =TAN(RADIANS(60)) gives 1.7320508075688767 that is similar to ${\sqrt {3}}$
The above function gives the Tangent of 'x' in Degree.

In a right angled triangle, TAN = Opposite side / Adjacent side or SIN / COS.
TAN function determines the Tangent of the given angle.
By default, Calci takes the angle in Radians.
To convert Radians to Degrees, multiply with 180/PI() or we have to use the Radians function like TAN(RADIANS(x)) or DTAN(x)
TAN(RADIANS(45))= 0.9999999999999999. i.e, approximately = 1. So for calculation we consider TAN(RADIANS(45))=1

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