Question

solve: dx/dt = cos(sqrt(t))/sqrt(t).

integration by parts: u = sqrt(t), du = (1/2)t^(-1/2)... not sure where to go from here. make dv = cos(u)dv and v = sin(u)?

Answer 1

Use a substitution \(u=sqrt(t)\)

Answer 2

I am almost done here -.-

Answer 3

do you have any questions?

Answer 4

nah- i was trying to use integration by parts instead of just straight u-substitution. thanks.
