Study Notes

  • Filgrastim stimulates the immune system

  • May result in a high risk of birth defect, in which case multiple birth control methods may be required

  • Integrals of indefinite forms:

  • $\int(x^5 - x^{2/3} + 2x^{-1/2})dx = \frac{x^6}{6} - \frac{3x^{5/3}}{5} + 4x^{1/2} + C$

  • $\int(x^2 + 1)(x-2)dx = \int(x^3 - 2x^2 + x - 2)dx = \frac{x^4}{4} - \frac{2x^3}{3} + \frac{x^2}{2} - 2x + C$

  • $\int \frac{x^3 + 1}{x+1} dx = \int (x^2 - x + 1) dx = \frac{x^3}{3} - \frac{x^2}{2} + x + C$

  • $\int (\sqrt{x} + \frac{1}{\sqrt{x}})dx = \int (x^{1/2} + x^{-1/2})dx = \frac{2}{3}x^{3/2} + 2x^{1/2} + C$

  • $\int (2\cos x - 3\sin x)dx = 2\sin x + 3\cos x + C$

  • $\int (\sec^2 x + x)dx = \tan x + \frac{x^2}{2} + C$

  • $\int (x^2 + \sec x \tan x)dx = \frac{x^3}{3} + \sec x + C$

  • $\int (5e^x - \frac{3}{x})dx = 5e^x - 3\ln|x| + C$

  • $\int (2^x + 3^x)dx = \frac{2^x}{\ln 2} + \frac{3^x}{\ln 3} + C$

  • $\int \frac{1}{x^2 + 1} dx = \arctan x + C$

  • $\int \frac{1}{\sqrt{1 - x^2}} dx = \arcsin x + C$

  • Integrals of definite forms:

  • $\int_0^1 (x - 2x^3)dx = [\frac{x^2}{2} - \frac{x^4}{2}]_0^1 = \frac{1}{2} - \frac{1}{2} - (0 - 0) = 0$

  • $\int_{-1}^0 (x - 2x^3)dx = [\frac{x^2}{2} - \frac{x^4}{2}]_{-1}^0 = (0 - 0) - (\frac{1}{2} - \frac{1}{2}) = 0$

  • $\int_1^2 (\frac{1}{x^2} - \frac{1}{x^3})dx = [-\frac{1}{x} + \frac{1}{2x^2}]_1^2 = (-\frac{1}{2} + \frac{1}{8}) - (-1 + \frac{1}{2}) = -\frac{3}{8} - (-\frac{1}{2}) = \frac{1}{8}$

  • $\int_0^1 (x^e + e^x)dx = [\frac{x^{e+1}}{e+1} + e^x]_0^1 = (\frac{1}{e+1} + e) - (\frac{0}{e+1} + 1) = \frac{1}{e+1} + e - 1$

  • $\int_0^{\pi/2} (4\cos\theta - 3\sin\theta)d\theta = [4\sin\theta + 3\cos\theta]_0^{\pi/2} = (4\sin(\frac{\pi}{2}) + 3\cos(\frac{\pi}{2})) - (4\sin(0) + 3\cos(0)) = (4(1) + 3(0)) - (4(0) + 3(1)) = 4 - 3 = 1$

  • $\int_0^{\pi/3} (\sec x \tan x)dx = [\sec x]_0^{\pi/3} = \sec(\frac{\pi}{3}) - \sec(0) = 2 - 1 = 1$

  • $\int_1^2 \frac{(x^2 + 1)^2}{x^2}dx = \int_1^2 \frac{x^4 + 2x^2 + 1}{x^2}dx = \int_1^2 (x^2 + 2 + \frac{1}{x^2})dx = [\frac{x^3}{3} + 2x - \frac{1}{x}]_1^2 = (\frac{8}{3} + 4 - \frac{1}{2}) - (\frac{1}{3} + 2 - 1) = \frac{7}{3} + 2 - \frac{1}{2} = \frac{14 + 12 - 3}{6} = \frac{23}{6}$

  • $\int_0^1 (\sqrt{x^5} + \sqrt{x^4})dx = \int_0^1 (x^{5/4} + x^{4/5})dx = [\frac{4}{9}x^{9/4} + \frac{5}{9}x^{9/5}]_0^1 = (\frac{4}{9} + \frac{5}{9}) - (0 + 0) = \frac{9}{9} = 1$

  • $\int_1^e \frac{x^2 + x + 1}{x}dx = \int_1^e (x + 1 + \frac{1}{x})dx = [\frac{x^2}{2} + x + \ln|x|]_1^e = (\frac{e^2}{2} + e + \ln e) - (\frac{1}{2} + 1 + \ln 1) = \frac{e^2}{2} + e + 1 - \frac{1}{2} - 1 - 0 = \frac{e^2}{2} + e - \frac{1}{2}$

  • $\int_0^1 \frac{1}{x^2 + 1}dx = [\arctan x]_0^1 = \arctan 1 - \arctan 0 = \frac{\pi}{4} - 0 = \frac{\pi}{4}$

  • $\int_0^{1/2} \frac{1}{\sqrt{1 - x^2}}dx = [\arcsin x]_0^{1/2} = \arcsin(\frac{1}{2}) - \arcsin(0) = \frac{\pi}{6} - 0 = \frac{\pi}{6}$

  • $\int_4^9 \frac{2 + \sqrt{x}}{x}dx = \int_4^9 (\frac{2}{x} + \frac{\sqrt{x}}{x})dx = \int_4^9 (\frac{2}{x} + \frac{1}{\sqrt{x}})dx = [2\ln|x| + 2\sqrt{x}]_4^9 = (2\ln 9 + 2\sqrt{9}) - (2\ln 4 + 2\sqrt{4}) = 2\ln 9 + 6 - 2\ln 4 - 4 = 2\ln 9 - 2\ln 4 + 2 = 2\ln(\frac{9}{4}) + 2$

  • Antibiotics necessitate taking all the medication

  • Cilluns and cyclines lessen the effect of birth control, so different birth control methods should be taken.

  • Stop alcohol consumption while taking antibiotics

  • Azithromycin consumption should be on an empty stomach

  • Sulfa medication requires no sun exposure, with lots of water, and folic acid. Urine should be monitored for kidney efficiency.

  • Myacin is very toxic, nephron and ototoxic, and kidney toxic. Urine output needs to be monitored.
