Answer:

tex]\frac{35}{16}[/tex]cosA

Step-by-step explanation:

     Given 4tanA=3

     so, 4sinA-cosA+1/4sinA+cosA-1

       Ans=  cosA[4tanA-1+1/4tanA+1-1]

               =cosA[3-1+\frac{1}{4}tanA]

        Now,

                    if 4tanA=3

                          tanA=4/3

                =cosA[2-\frac{1}{4}×\frac{3}{4} ]

                =\frac{35}{16}cosA
