d cot x = (csc x)2 . dx d sec x = sec x tan x. 5. dx d csc x = csc x cot x. 6. dx 4. C. Derivatives of lnx and ex : We conclude our library of derivatives of basic functions with d x e = ex dx and 1 d ln x = . dx x We may apply the Chain Rule to obtain the following particularly useful generalization of this logarithmic derivative: (x) d ln (x) = . dx (x) Now it is time to learn to differentiate the functions that we will commonly encounter in our work. We do so by applying the rules for sums, products, quotients, and compositions to the formulas for the derivatives of the elementary functions. Practice is the essential tool in mastery of these ideas. Be sure to do all the You Try It problems in this section.

The semi-translucent clinical appearance is a clue that the lesion could be a basal cell carcinoma. This case points out that basal cell carcinomas can have polymorphous vessels in addition to typical arborizing vessels. The irregular gray blotches (homogeneous gray color) are the pigmented component of the basal cell and not a criterion that can diagnose a melanocytic lesion. There are two components to the ulceration: Ulceration Dried dark blood There appears to be vessels in the ulceration, which is unexplained and has a differential diagnosis: An irregular dark blotch of a melanocytic lesion with polymorphous vessels. Ulcerations can be found in both basal cell carcinomas and melanomas, and are not a differentiating point. Statistically, ulcerations are more commonly found in basal cell carcinomas. The final thought after evaluating all of the clinical and dermoscopic criteria is that this could be a melanoma with ulceration and polymorphous vessels, or an unusual basal cell carcinoma with polymorphous vessels and lacking classic arborizing vessels. Either way, prompt histopathologic diagnosis is indicated.
