In a 60 degree right triangle, x-axis = 1 and y-axis = Sqrt(3).
In degree mode, Tan(60) = Sqrt(3).
In radian mode, Tan(60 x Pi / 180) = Sqrt(3)
60 x Pi / 180 is the arc length between 60 degree angle.
Therefore, there is a direct relationship between arc length and x & y
length for each triangle.
Given with any x and y lengths for a right triangle, I would like to
determine the arc length based on this relationship.
Does anyone have any suggestions on how to determine the formula to
calculate the arc length?
In this example, x =1 in cell A1 and y = Sqrt(3) in cell B1, I would like to
determine the arc length = Pi / 3 in cell C1.
Does anyone have any suggestions?
Thanks in advance for any suggestions
