df(x)=(ln(3.4x))*(arcsin(3.4x))

Solution for df(x)=(ln(3.4x))*(arcsin(3.4x)) equation:

Simplifying
df(x) = (ln(3.4x))(arcsin(3.4x))

Multiply df * x
dfx = (ln(3.4x))(arcsin(3.4x))

Remove parenthesis around (3.4x)
dfx = (ln * 3.4x)(arcsin(3.4x))

Reorder the terms for easier multiplication:
dfx = (3.4ln * x)(arcsin(3.4x))

Multiply ln * x
dfx = (3.4lnx)(arcsin(3.4x))

Remove parenthesis around (3.4lnx)
dfx = 3.4lnx(arcsin(3.4x))

Remove parenthesis around (3.4x)
dfx = 3.4lnx(acinrs * 3.4x)

Reorder the terms for easier multiplication:
dfx = 3.4lnx(3.4acinrs * x)

Multiply acinrs * x
dfx = 3.4lnx(3.4acinrsx)

Remove parenthesis around (3.4acinrsx)
dfx = 3.4lnx * 3.4acinrsx

Reorder the terms for easier multiplication:
dfx = 3.4 * 3.4lnx * acinrsx

Multiply 3.4 * 3.4
dfx = 11.56lnx * acinrsx

Multiply lnx * acinrsx
dfx = 11.56aciln2rsx2

Solving
dfx = 11.56aciln2rsx2

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Divide each side by 'fx'.
d = 11.56acf-1iln2rsx

Simplifying
d = 11.56acf-1iln2rsx
