I have to program the range formula R= [Vo2sin(2*theta)]/g, into an Excel spredsheet. I need to progran the equation for various values of 'theta' to determine for which value(s) of 'thet' is the range maximum. Table should have left side Injection angle (degrees), right side Range (R). The injection angle will go from 0 to 90 degrees in steps of two degrees. Problem = I do not know Excel! Can someone help me on this?
