Spread of a Virus. Dengue fever, an illness carried by mosquitoes, is occurring in one of the worst outbreaks in decades across Latin America and the Caribbean. In 2004, 300,000 cases were reported, and 630,000 cases in 2007. How many cases might be expected in 2013? (Let t 0 be 2004.) Use the formula N N0ert, where N represents the number of cases.

Section 3.7: Derivatives of Inverse Trig Functions Inverse Sine: y=sin (x) y=arcsin(x) o Inverse Sine can be written: or −π π o For this inverse: −1≤x≤1 and 2 ≤y≤ 2 In other words, x is greater than or equal to 1 and less than or equal to 1 and y is greater than or equal to −π 2 π and less than or equal to 2 . −π π o Inverse Sine is the angle (in radians) between
