I am working on some homework and am stuck when it comes to problems like these:
Find ds/dt if s=ln[t^8(t^7-2)]
Thanks for the help!
You can follow what Archie meade said or:
Let u=t^8(t^7-2)=t^15-2t^8
So:
D(ln(u))=D(u)/u=(D(t^15-2t^8))(/t^15-2t^8)
If you can calculate this derivative: D(t^15-2t^8) then you are finished (you can also simplify the fraction).
