Find a particular solution to y" - y' + 9y = 3 sin 3x

cos3x

Step-by-step explanation:

y" - y' + 9y = 3 sin 3x

here will be replaced by   where is coefficient of x

y=cos3x

hence Particular solution is cos3x

5 3200sq,ft

80+60+y=180

then divide the difference between 60 and y and add it to 180

so x =180 +( (y-60)/2)

x equals 200
