The convenient way to calculate limits is using L' Hospital's Rule

Description
L'Hospital's rule is discussed with the help of examples. The convenient way to calculate the limits, including the new one's are discussed here. All the indeterminate forms of limit, the difference quotient and the moving exponent are is defined.
