Finding Values of x for Trig EquationDate: 9/11/96 at 9:34:45 From: Anonymous Subject: Finding Values of x for Trig Equation How do I find the values of x to make: tan x = -x/((16-x^2)^.5)) true? I tried to use a computer program, but couldn't get the program to work. Date: 9/11/96 at 16:26:42 From: Doctor Robert Subject: Re: Finding Values of x for Trig Equation Try doing it with a graphing calculator. Graph y = tan x and y = -x/sqrt(16-x^2) and ask for the intersection. There are several points of intersection. My calculator (TI-92) says that one of them is (-2.4746,.7874) -Doctor Robert, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
