Tính 1/1 + 1/2 + 1/3 + 1/4 +...+ 1/190

To find the sum of the series 1/1 + 1/2 + 1/3 + 1/4 + ... + 1/190, we can use the formula for the sum of a harmonic series:

S = 1/1 + 1/2 + 1/3 + 1/4 + ... + 1/n

where S is the sum and n is the number of terms.

In this case, n = 190, so we can substitute it into the formula:

S = 1/1 + 1/2 + 1/3 + 1/4 + ... + 1/190

S = 1/1 + 1/2 + 1/3 + 1/4 + ... + 1/190

S = 1/1 + 1/2 + 1/3 + 1/4 + ... + 1/190

To calculate this sum, we can use a calculator or a computer program. The sum is approximately 5.87855.
