WebTo create a direction field, we start with the first equation: y′ = 3x + 2y − 4. We let (x0, y0) be any ordered pair, and we substitute these numbers into the right-hand side of the differential equation. For example, if we choose x = 1andy = 2, substituting into the right-hand side of the differential equation yields. WebWhen the direction field is shown, click on the "initial point" to sketch the graph of the solution passing through the point. Drag the initial point to move it to a different …

WebIn Mathematica, the only one command is needed to draw the direction field corresponding to the equation y' =1+t-y^2: dfield = VectorPlot [ {1,1+t-y^2}, {t, -2, 2}, {y, -2, 2}, Axes -> … WebThen the slope field will be independent of y. It will look like a lot of "columns" of lines all with the same slope. So on the x-axis the lines will be horizontal, for x=1/2 they'll be diagonal lines, etc. We can solve dy/dx = 2x directly (by integration), giving y = x² + C.
