College Algebra - We continued our discussion of the procedures employed for graphing the secant and cosecant functions. HW for Monday - Graph the following equations on the graph paper provided in class (also available online):

9:00
y = -2 csc (x - pi/4) - 1
y = 3 sec 1/2 (x + pi/2)

11:00
y = 1/2 sec 4(x) - 2
y = -2 csc (x - pi/4)

Note: These graphs will be collected in class on Monday.

Accl. Geometry - We concluded our discussion of basic area formulas, focusing on Heron's Formula for finding the area of a triangle. HW for Monday - Complete the Heron' Formula worksheet distributed in class and the area review packet distributed in class. Review for Monday's quiz covering Sec. 8.1 - 8.3.
