(ii) Differentiate y=x^(3) sqrt( 3x -4)

Differentiate by first principle f(x)=sqrt(3x+4)

if A and B are matrices of same order, then (AB'-BA') is a 1) null matrix 3)symmetric matrix 2) skew -symmetric matrix 4)unit matrix

Differentiate sin^(-1){(sinx+cosx)/(sqrt(2))},\ -(3pi)/4

Find the inverse of the matrix A=[1 3 3 1 4 3 1 3 4]

If a rank is a number associated with a matrix which is the highest order of non-singular sub matrix that prove that Rank of the matrix A=[{:(,1,3,-2),(,4,-1,0),(,2,-7,4):}]"is "2
