Trig (B5):
three verification problems:
1)(secx+tanx)/(secx-tanx) = (1+2sinx+sin^2x)/(cos^2x)
3)(secx-tanx)^2=(1-sinx)/(1+sinx)
6)(secx-cscx)/(secx+cscx) = (tanx-1)/(tanx+1)

** make fractions into vertical fractions...

Stats (B6):
no homework


PreCalc (B8):
#4: pg. 213 #7, 19, 25, 35, 45, 51, 53, 55, 77-85odd
