Secant Function a. Sketch two cycles of the parent cosine function y = cos . Use the fact that sec = to sketch the graph of y = sec . b. How can you locate the asymptotes in the secant graph by looking at the cosine graph? How does your graph compare with the secant graph in Figure 3-3b? c. Does the secant function have critical points? If so, find some of them. If not, explain why not. d. Does the secant function have points of inflection? If so, find some of them. If not, explain why not.

Types of plasma proteins: 1. Albumins: contribute to the plasma's osmotic pressure (water pressure, like little sponges that absorb the water so that it doesn't leak out of veins), found in egg whites 2. Globulins: antibodies, hemoglobin(provide oxygen), etc (like an archer's arrows that are made of globulin, that attack any virus or pathogen) 3. Fibrinogen: forms blood clots when activated, blood
