# goniom(A) plots an A degree angle (with an automatic scale) or, better: # draws a quarter of goniometer, plots the angle, displays the coordinates of the # corresponding point of the circle and the corresponding slope goniom(45) goniom(60) goniom(30) # The ordinate of the grey point is the same as the slope. goniom(26.565) # With gonioM(a), you can choose (by using BF and HF) other scales. # # goniome(S) plots the angle that has the slope equal to S # A 40 m high tower projects a 24 m shade (40/24 = 166.67%): goniome(40/24) # With gonioMe(a), you can choose (by using BF and HF) other scales.
