Clinical psychologists work with patients who have mental, emotional and behavioral disorders. The field represents a prominent specialty within the broad field of psychology.ducation and Training. Clinical psychologists typically have a doctorate, usually a Psy.D. degree, which is a doctor of psychology. Some obtain a Ph.D., which is a doctor of philosophy.
In short, to find a limit graphically, you simply follow the graph horizontally, until you reach the desired x-value, at which point you then look to see the what the corresponding y-value is, or is approaching. To be more specific, suppose you are looking for the limit as x approaches from 5 from the RIGHT side of #y=x^2#.
For instance, when evaluating the limit Sin[x]^x (which is 1 as x goes to 0), we say it is equal to x^x (since Sin[x] and x go to 0 at the same rate, i.e. limit as x->0 of Sin[x]/x is 1). Then we can see from the graph of x^x that its limit is 1. Other than the times when we want it to be indeterminate, 0^0 = 1 seems to be the most useful choice for 0^0 . This convention allows us to extend definitions in different areas of mathematics that would otherwise require treating 0 as a special case.
