Algebra.Com's Answer #95989 by stanbon(75887) ![]() You can put this solution on YOUR website! have a TI-83 and I want to know how to graph a Logarithmic spiral with the geometric progression of 1.4. \n" ); document.write( "I believe the equation is: \n" ); document.write( "r = ae^(b[theta]) \n" ); document.write( "In fact I want to know how this spiral can be graphed by hand... \n" ); document.write( "-------------- \n" ); document.write( "Your equation is an exponential equaation. \n" ); document.write( "It is either an increasing function (b>1) or a decreasing \n" ); document.write( "function (0 < b < 1) \n" ); document.write( "---------------- \n" ); document.write( "You will not get a spiral graph out of it because the \n" ); document.write( "TI-83 uses the Real Number line as its domain. \n" ); document.write( "---------------- \n" ); document.write( "If you want theta to run from 0 to 2pi and then 0 to 2pi \n" ); document.write( "repeatedly you would have to plot your points and see \n" ); document.write( "how the curve is affected. \n" ); document.write( "--------------------------------- \n" ); document.write( "Also, keep in mind, the TI can only plot functions. If \n" ); document.write( "there are two or more y values associated with any x-value \n" ); document.write( "the TI cannot graph it. \n" ); document.write( "---------------------------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
