The correct answer is y= e^-2t (c1.cos(t) + c2.sin(t))

Dude here asking real questions Not some bitchy shit like my girlfriend hates me, boyfriend and I are getting apart blah blah blah...

Guys don't make jokes he got a real question here If y" +4y + 5y= 0 hence y' and y" are the first and the second u will add 5 with 4 and y by y and then u will shove it up ur ass😂😂😂😂 The office fans By: Anonymous 🎖 5 rep a few seconds ago

Use implicit differentiation. "Larson calculus" this book will help you alot

Try finding soft copy of applied mathematics 3,,it's all there

I meant y" is one and 4y' is 4

Y"is o and4y' is 4 then do the rest

y" is equivalent to 45^y hence 4y' + 5y' is almost 1% of £lan 3 subtract 6y for sin x and add 0 so it will beome 4'y + 5' and fuck u too

Why are u posting all this math questions ... go read a book

Nerddd alert😜😜
