Hello
Andrew,
If you
are using a computer Windows, you have a scientific calculator that
calculates these trig functions. Go to "Start" then "Programs" then
"Accessories" and "Calculator". If the calculator shown is standard, choose the
scientific calculator by going to "View" and checking "scientific". You will see
buttons for sin, cos and tan. For the arcsin, arccos and arctan, check the Inv
box for the inverse functions. For example put in .5 and check Inv and click on
sin to get the answer 30. as arcsin 0.5 = 30, as sin 30 = 0.5.
Enjoy,
Roger Bailey

Subject: Question on calculating arcsinI am in the early stages of designing a sundial for my bedroom window. I used a GPS unit to determine the latitude and the declination of the window.I went onto "The Sundial Primer" by Carl Sabanski and downloaded how to design a Vertical Declining Dial. According to "Sundials their Construction and Use" by Mayall and Mayall this is the type of dial for my window. This book is proving to be very helpful.I need the formulas or a website for the formulas for calculating arcsin and arctan.I am still working out the design but I think it will look pretty cool in a window.When I get it done I will do a posting somewhere of it, and let you know what happened.Sincerely,Andrew
