dy/dx = dy/dx = y-1 2-1 x2 22 (1/4) (-1/4) Part (a) Let’s start with a random point—(2,2) for example... Repeating this process8 more times gives usour slope field. m=1/4
dy/dx = y-1 x2 ln y-1 = -x-1 + C ln y-1 = -x-1 + 1/2 ln 0-1 = -2-1 + C -1 x ( +½) ln y-1 e = e Part (b) Separate the variables (y-1)-1= x-2 dx Integrate both sides Find the value of C 0 = -1/2 + C C = 1/2 Exponentiate both sides
-1 ( +½) 2 e = 0 1 = e y-1 e0 = 0 1 e = y-1 e = y 1 e = 1- y -1 -1 -1 -1 -1 x x x x x ( +½) ( +½) ( +½) ( +½) ( +½) ln y-1 Part (b) 1 Use the negative part. e = e
lim e 1- x 1 – e = e = 1- y -1 -1 x x ( +½) ( +½) Part (c) = 1 – e0+½ = 1 – e½
