The Essence of Discovery--
"Live Your Life Each Day As You Would Climb A Mountain.
An Occaional Glance Towards The Summit Keeps The Goal In Mind
But Many Beautiful Scenes Are To Be Observed From Each New Vantage Point.
Climb Slowly, Steadily, Enjoying Each Passing Moment,
And The View From The Summit Will Prove To Be Astonishing."
How to compute slope distance from horizontal distance & vertical angle
1. The formula is cos (angle) = HD/SD
2. Then, SD = HD/cos (angle)
3. SD = slope distance
4. HD = Horizontal distance
5. angle = slope angle
Please take note that vertical angle is 90 degree when it is horizontal, up is less than 90 degree.
