Lim e ^ x-e ^ SiNx / Tan ^ 2xln (1 + 2x) (x tends to 0)

Lim e ^ x-e ^ SiNx / Tan ^ 2xln (1 + 2x) (x tends to 0)

Obviously, when x tends to 0, TaNx is equivalent to x, ln (1 + x) is equivalent to x, so denominator (TaNx) ^ 2 * ln (1 + 2x) is equivalent to x ^ 2 * 2x = 2x ^ 3, and molecule e ^ X - e ^ SiNx = e ^ SiNx * [e ^ (x-sinx) - 1] then SiNx tends to 0, e ^ SiNx tends to 1, and X is equivalent to SiNx, that is, x-sinx tends to 0, so e ^ (x-sinx)
