" (iii) "(a)/(x^(4))-(b)/(x^(2))+cos x

Find derivative of the following functions (it is to be understood that a,b,c,d,p,q,r and s are fixed non-zero constants and m and n are integers): (a)/(x^(4))-(b)/(x^(2))+cos x

Find the derivative of the following functions a/x^(4) - b/x^(2) + cos x

Lt_(x to 0)(64)/(x^(4))(1-"cos"(x)/(2)-"cos"(x)/(4)+"cos"(x)/(2)."cos"(x)/(4))=

Find the derivative of a/x^4 - b/x^2 + cos x

" Let "a=min{x^(2)+2x+3,x in R}" and ", b=Lt_(x rarr0)(64)/(x^(4))[1-cos(x/2)-cos(x/4)+cos(x/2)cos(x/4)] then find the value of a and b

Let a=min{x^(2)+2x+3,x in R} and b=lim_(xto0)(64)/(x^(4))[1-cos(x/2)-cos(x/4)+cos(x/2)cos(x/4)] then

Find the derivative of the following function (it is to be understood that a, b, c, d,p, q, r and s are fixed non-zero constants and m and n are integers): a/x^4-b/x^2+cos x

If f(x)sin x cos xdx=(1)/(2(b^(2)-a^(2)))ln f(x)+c, then f(x) is equal to (1)/(a^(2)sin^(2)x+b^(2)cos^(2)x)(b)(1)/(a^(2)sin^(2)x-b^(2)cos^(2)x+b^(2)cos^(2)x+b^(2)cos^(2)x)(d)(1)/(a^(2)cos^(2)x-b^(2)cos^(2)x)
