simplify ln(1/(1+x^2))

Solution

simplify

ln (\frac{1}{1 + x ^{2}})

Solution

- ln (x^{2} + 1)

Solution steps

ln (\frac{1}{1 + x ^{2}})

Apply log rule:

lo g_{c} (\frac{a}{b}) = lo g_{c} (a) - lo g_{c} (b)

ln (\frac{1}{1 + x ^{2}}) = ln (1) - ln (1 + x^{2})

= ln (1) - ln (x^{2} + 1)

Apply log rule:

lo g_{a} (1) = 0

= 0 - ln (x^{2} + 1)

0 - ln (1 + x^{2}) = - ln (1 + x^{2})

= - ln (x^{2} + 1)
