For example, if a thrown exception object has class IllegalArgumentException, that indicates someone passed an illegal argument to a method. Sometimes you will want to indicate that a method encountered an abnormal condition that isn't represented by a class in the Throwable family of java.lang.
Actually, zero is neither a negative or a positive number. The whole idea of positive and negative is defined in terms of zero. Negative numbers are numbers that are smaller than zero, and positive numbers are numbers that are bigger than zero. Since zero isn't bigger or smaller than itself (just like you're not older than yourself, or taller than yourself), zero is neither positive nor negative.
The first term in the numerator and denominator will both be zero. However, the z 3 in the numerator will be going to plus infinity in the limit and so the limit is, The final limit is negative because we have a quotient of positive quantity and a negative quantity. Now, letâs take a look at the second limit. Note that the only different in the work is at the final âevaluationâ step and so weâll pick up the work there. In this case the z 3 in the numerator gives negative infinity in the limit since we are going out to minus infinity and the power is odd.
