Use the differential equation to find the slope of the tangent line to the solution yt at t 0. Slope sometimes referred to as gradient in mathematics is a number that measures the steepness and direction of a line or a section of a line connecting two points and is usually denoted by m. Sketch this tangent line over the interval -025 leq t leq 025 on the axes provided.
The slope yx of the solutions yx is determined once we know the values for x and y eg if x1 and y-1 then the slope of the solution yx passing through the point 1-1 will be.
B Use integration to find the particular solution of the differential equation and use a graphing utility to graph the solution. Sketch this tangent line over the interval -025 leq t leq 025 on the axes provided. Use the differential equation to find the slope of the tangent line to the solution yt at t 0.
