Find the limit of (TaNx / x) ^ (1 / x ^ 2) when x tends to 0 Using the law of Robida, the answer is e ^ 1 / 3,

Find the limit of (TaNx / x) ^ (1 / x ^ 2) when x tends to 0 Using the law of Robida, the answer is e ^ 1 / 3,

Let y = (TaNx / x) ^ (1 / x ^ 2) take the logarithm LNY = {ln (TaNx / x)} / x ^ 2 at the same time, and use the law of lobita to get: the numerator: 1 / sinxcosx - 1 / X denominator 2x is transformed into {x / (2sinxcosx)} * {(x-sinxcosx) / x ^ 3} and then use the law of Robita to get (1 / 2cos2x) {(1-cos2x) / 3x ^ 2} = (1 / 2
