CHAPTER 1 - FIRST ORDER DIFFERENTIAL EQUATIONS

dy dx = y; y = Cex where C is an arbitrary constant (b) dy dx = 3ex; y = 3ex +C where C is an arbitrary constant (c) y(3) 3y0+2y = 0; y = e 2x (d) dy dx = (x +1) y 3; (x +1)2 +(y 3)2 = c2, where c is an arbitrary constant. (e) d2y dt2 +k2y = 0; y = sinkt, where k is a constant DIFEQUA DLSU-Manila ................
