Reminders for today:

PHY:
- Physics Long Test is Tomorrow. Coverage is Work, Enrgy, and Power(self-study on Power)
- For consultation purposes, answer the question below:

p. 146 of Giancolli, 3rd Edition, # 38)
(II) A ski starts from rest and slides down an 18° incline 80 m long.
(a) If the coefficient of friction is 0.080, what is the ski's speed at the base of the incline?
(b) If the snow is level at the foot of the incline and has the same coefficient of friction, how far will the ski travel along the level? Use energy methods.

BIO:
- Please read up on:
1) epidermis
2) dermis
3) hypodermis
4) stratum sorneum
5) s. germinavitum
6) s. lucidum
7) s. spinosum
8) s. basale
9) s. granolosum

- BIO Quiz about the skeletal system tomorrow.

MATH:
-HW5:

Express in the form of a+bi, where a and b are real numbers:

48) 8(cos(7π/4) + i sin(7π/4))
50) 12(cos(4π/3) + i sin(4π/3))
52) 3(cos(3π/2) + i sin(3π/2))
54) √(53) cis(tan^-1(- 2/7))
56) √(10) cis(tan^-1 3)

Use trigonometric forms to find z₁z₂ and z₁/z₂:

58) z₁= √(3) - i
z₂=1+i

60) z₁= -5 + 5i
z₂=-3i

62) z₁= 2i
z₂=-3i

64) z₁=-3
z₂=5 + 2i
