Area of a circle "ds" over the whole circle formula_33 is just the arc length, which is its circumference, so this shows that the area "A" enclosed by the circle is equal to formula_34 times the circumference of the circle. Note that the area of a semicircle of radius r can be computed by the integral formula_35. By trigonometric substitution, we substitute formula_36, hence formula_37 The last step follows since the trigonometric identity formula_42 implies that formula_43 and formula_44 have equal integrals over the interval formula_45, using integration by substitution. But on the other hand, since formula_46, the sum of the two integrals is
What Is a Man Without a Moustache? 62 based on five reviews from critics. In a review for "Variety" magazine, critic Deborah Young called "What Is a Man Without a Moustache?" "an entertaining romantic comedy" and a "good-humored film" while, on the other hand, noting that the film should be better received by local and regional audiences due to its story being "a hard sell abroad". Author and film critic Michael Atkinson, writing for "The Village Voice", expressed his divided opinion that the film "is not remarkable or ingenious" but that it still is "adept enough for a pass on." Critic Nathan Lee of "The New York
