Question 4 Questions 4.1-4.3 are multiple choice questions. In each of those questions you will classify a given differential equation as one from the list. Classification is an important step in solving an equation because the methods of solution vary significantly for equations of different type. Question 41 Classify the type of the differential equation Question 4.2 Classify the type of the differential equation Question 43 Classify the type of the differential equation 1231' + (1 + sing) cos: = O as in: 233/7 S =(ziy)cosz {112 (:1 223; 213; = 3 i d:- :c as as O homogeneous O exact 0 linear O separable O Bernoulli equation 0 both linear and exact 0 both linear and separable 0 both Bernoulli and separable 0 not listed here Q Bernoulli equation 0 exact 0 linear O homogeneous O separable 0 both linear and exact 0 both linea r and separable 0 both Bernoulli and separable 0 not listed here 0 linear O Bernoulli equation 0 separable O exact O homogeneous 0 both linear and exact 0 both linear and separable 0 both Bernoulli and separable Onot studied in MTH220
