## int( x/(a^2-x^2), x)...

Maple

Dear Users,

Maple is giving the result for the following integration as

int( x/(a^2-x^2), x)  = -ln(-a^2 + r^2)/2

However, I presume the integral output should be -ln(a^2 -  r^2) /2

Could any one comment on this issue.

## Roots of a sextic polynomial...

Maple

Dear Experts,

I am in a process of trying the roots of a sextic polynomial.

Attached is the equation type  sixthorderpolynomial.mw  . I tried to do some simplification. But still not able to find the solution.   I tried to use Factor also. But no progress.

I am intended to get the solutoin for lambda variable and remaining are variables are constants.

## Maximum of a function of three variables...

Maple

Dear Maple experts,

I have a function f  depending on three variables a,b,c i.e.   f(a,b,c).

I have to find the df/da (differentiation  with respect to a) and then solve for variable a in terms of variables b and c to make the f(a,b,c) into f(b,c).

However, I am not able to find the symbolic relation from df/da to represent variable a interms of variables b and c because the solve(df/da, a) is...

Dear Experts,

I have an equation which needs to be simplified. However it is mostly in Bessel I and BesselK. To simply it I have used the simplify( expression,

## Finding zero slope of an implicit functi...

Maple

Dear All,

I have an implicit function f(x,y) in terms of special functions. I need to optimize it.  So  I plotted it and found the location of the zero slope. However I cannot get the precise value of x and y, where the slope equals  zero.

Is there any better option to get the location of x and y, where the slope is zero?
