Unformatted text preview: • Do solutions display any periodicity? We know sin( t ) has period of 2 π and solution curve repeats itself. Here large interval for t might be needed. You can use the following functions • f ( t,x ) = sin ( x ) • f ( t,x ) = cos ( t ) • f ( t,x ) = x ( x1) • f ( t,x ) = e t x + sin ( x ) • f ( t,x ) = x + xsin ( t ) You should use the provide Mathcad ﬁle at the website www.unf.edu/ ∼ mzhan/vectorﬁeld.mcd as a starting point and superimpose solutions to the vector ﬁelds so support your observation....
