f(t) =3-t^4 and g(t)=sin(4t)

Then using the Quotient Rule differentiate the function

k(t) 3-t^4/ sin(4t) (0<t< pie)

g'=d/dt (sin(4t))= cos4t * d4t/dt=4cos4t

ARRRRGGG. Quotent rule in ASCII

That is too much algebra for me to do now, maybe later.

**Reiny**, Sunday, February 13, 2011 at 9:09am2nd question:

first line derivative

= [ -4t^3(sin(4t)) - 4cos(4t)(3-t^4) ] / (sin(4t))^2

after that there are several things you could do, I don't know what kind of answer your course is expecting.

you could split it up into two fractions ...

= (-4t^3)/sin(4t) - 4(3-t^4)cot(4t) / sin(4t)

as one possibility
