In this problem, y = c1 cos 3x + c2 sin 3x is a two parameter family of solutions of the second-order DE y?? + 9y = 0. because sin(3x) is not the product of something called sin with 3x, so you can't “cancel the sin's”: sin(3x) sin(x3 + 2). 6= 3x x3 + 2 . Of course, you can ... Jan 1, 2021 ... olution: We have VV​=πr2h,r=0.5 m,dtdV​=1060.25​ m3/min=π×0.25×h⇒dtdV​=π×0.25×dtdh​⇒1060.25​=π×0.25×dtdh​⇒dtdh​=106π1​ m/min​ imple 26 The ... May 14, 2015 ...
