Tan Function

កំណត់តង់សង់របស់មុំមួយ ។ មុំត្រូវបានបញ្ជាក់ជារ៉ាដ្យង់ ។

Using the angle Alpha, the Tan function calculates the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle in a right-angled triangle.

Tan(Alpha) = side opposite the angle/side adjacent to angle

Syntax:


Tan (Number As Double) As Double

Return value:

Double

Parameters:

ចំនួន ៖ កន្សោមលេខមួយចំនួន ដែលអ្នកចង់គណនាតង់សង់ (គិតជារ៉ាដ្យង់) ។

To convert degrees to radians, multiply by Pi/180. To convert radians to degrees, multiply by 180/Pi.

degrees=(radians*180)/Pi

radians=(degrees*Pi)/180

Pi is approximately 3.141593.

Dim d1 As Double
Dim dAlpha As Double
    d1 = InputBox("Enter the length of the side opposite the angle: ","opposite")
    dAlpha = InputBox("Enter the Alpha angle (in degrees): ","Alpha")
    Print "the length of the side adjacent the angle is"; (d1 / tan (dAlpha * Pi / 180))
