Work Description:
|
This is the math classroom of Prof. Ira De Long and it probably is in Main. Above the desk at the left is a chart of trigonometric identities. In the cabinet are string and plaster models of various mathematical surfaces. On the board are the steps in deriving the expression for the nth derivative with respect to x of y = tan^-1(1/x). On the right board is a problem in plane trigonometry, "Find Height of Fort". It is interesting to note the details of the calculations which use six place logarithms to the base 10. An error has been made in the line "∆BED log c = 2.285874". This should be 2.285974 with the result that the answer should be 136.60 ft. while they give 136.59. Using his incorrect answer for log c gives a final answer 136.57 ft. which is off more than it should be for calculation with six place logarithms. Above the boards are a table of relations in spherical trigonometry and a picture of Isaac Newton. This would seem to be room 209 in the NW corner of the second floor of Main. No trace remains of the cabinet with models or of the ornate iron register, although the duct to serve the register is available in the next room east. A thermometer hangs on the right frame of the closet.
