Tyler! Help me please!

there is no tyler here... only fatalbone.(solved by my engineer friend)

d)you made a mistake missing a - or - minus in equation
e)solveable now but ugly algebra
 dv/dt+0.1-v^2=10-->dv/dt=10^2/10-v^2/10
dv/((10^2-v^29/10)=dt-->(10/((10-v)(10+v))(dv/dt)=1 you can find from there looking to answer.

f)(1/(10-v)+1/(10+v))dv=2dt--> integral(1/(10-v))dv+int(1/(10+v))dv=int(2)dt

-ln(10-v)+ln(10+v)=2t

ln((10+v)/(10-v))=2t

e^ln((10+v)/(10-v))=e^2t

(10+v)/(10-v)=e^2t

you should be able to solve from here even I managed to solve f. These questions are easy differentials but very ugly algebra.

you should get v=(10e^2t-10)/(1+e^2t)

Me r scared of this talk!

two times nothing equals nothing, worm was never there!

lul necro!

Wasn't that hard actually, solved it some time ago but I don't have a scanner =(

(looks too messy in computerwriting)
