Ex 9.1, 4 Determine order and degree (if defined) of differential equations given 𝑑﷮2﷯𝑦﷮𝑑 𝑥﷮2﷯﷯﷯﷮2﷯+𝑐𝑜𝑠 𝑑𝑦﷮𝑑𝑥﷯﷯=0 𝑑﷮2﷯𝑦﷮𝑑 𝑥﷮2﷯﷯﷯﷮2﷯+ 𝑐𝑜𝑠 𝑑𝑦﷮𝑑𝑥﷯﷯=0 ∴ 𝑦﷮′′﷯﷯﷮𝟐﷯+ 𝑐𝑜𝑠 𝑦﷮′﷯﷯=0 Highest Order of Derivative =2 Order =𝟐 Degree :- Since 𝑦﷮′﷯ is in 𝑐𝑜𝑠 𝑦﷮′﷯﷯ It is not a Polynomial equation in derivative ∴ Degree is Not Defined
