I. Finding the altitude of your rocket. A. Method 1: Trigonometry - The easiest (and least accurate) way to calculate the height of your rocket at its apogee is by using pythagorean theorem. One can use the tool pictured to the right to determine the angle of incline of the apogee for any given distance away from the rocket launch. The student can ? Distance Alt Point at Rocket Take Reading Here stand a distance d away from the launch and point the altitude finder at the apogee as shown in the picture below. Question: Using this arrangement describe in a paragraph below (using words, equations, and/or pictures) how someone would find the height of their rocket using trigonometry (specifically SOHCAHTOA). Then derive a formula for the altitude (again, using SOHCAHTOA).
