Question

Your answer is incorrect. Find the general solution to y' + 20t19 y = t20 . Use the variable I = | e dt where it occurs in your answer, since this integral is not easily computable. Note that the arbitrary constant C would come from actually computing the integral I, so you do not need to write it. t t9 (19 et") when computing integral in the general solution. Hint: You will want to rewrite t20 et

Geiven. De is The y'+ 204 y = 20 to factor to (1) is integrating I.Fe 520419dt Multiply Il by I..., we get * 20 loko 20 je dleto). 4206+ et by separation of 20 1 . variables Integrating, we get 0.420 y = 120 120 It I t e =5+(419 ct?) de em 20 ot se v-S 41 Stalet Bebt, by integration by parts parts 20 , 20 . leider zitie 0 - dt 20 - goedtoe tot using 1- Semaran ox ero dt
