Differentiate with respect to x: y=(6x^2-1)/2sqrt(x)

1st Step: Must separate the fractions and simplify: y= (6x 2 -1)/2sqrt(x)= 6x 2 /(2x 1/2 ) - 1/(2x 1/2 ) Cancel 6 with 2 and x 2 with x 1/2 => y= 3x 3/2 - x -1/2 /2 2nd Step: Differentiate: dy/dx= (9/2)x ...

i) It is given that f(x)=(-5-33x)/((1+x)(1+5x)), express f(x) in the form A/(1+x) + B/(1+5x) where A,B are integers. ii) hence express the integral of f(x) between x=3 and x=0 in the form (p/q)ln4 where p,q are integers.

i) -7/(1+x) + 2/(1+5x) ii) (-31/5)ln4
