11) f(t)=(1)/(sqrt(8t-3))

12) g(t)= ((4t-3)^2)/ ((5t+1)^4)

Thanks.

**bobpursley**, Wednesday, June 15, 2011 at 6:06pmThese are standard formulas...

f()= 1/u

f'=-u'/u^2 where u is sqrt(8t-3), u'=4/sqrt( )

g= u/v

g'=-uv'/v^2 + u'/v where u=(4t-3)^2 v=(5t+1)^4

I assume you can do it from here.
