Packet 7: Tossup 14

This function of a complex number, z, is defined as this function of its modulus plus i times theta. The number of primes less than or equal to (15[1])a real number (-5[1])n is approximately (15[2])n over this function (15[1])of n. The alternating harmonic series converge to this function of 2. This function of n (*) factorial can be approximated using Stirling’s approximation. (10[1]-5[1])The first three terms of the Taylor series of this function of 1 plus x is x minus x squared over 2 plus x cubed over 3. This function’s derivative is 1 over x. For 10 points, name this function whose inverse is e to the x. ■END■ (0[1])
