Wednesday  October  30	Topics:	7.2,  Right Triangle Trigonometry, pg.  593		
7.2  - pg 593,  Learning Objectives
	* Use right triangles to evaluate trigonometric functions.
	* Find function values for 30° (pi/6), 45°(pi/4), and 60°(pi/3).
	* Use equal cofunctions of complementary angles.
	* Use the definitions of trigonometric functions of any angle.
	* Use right-triangle trigonometry to solve applied problems.
Notes:	
10.30.a,  trig functions of he 30s,45s,  60s
10.30.b,  OSCAR connect the dots
 10.30.c,  angle &  side connect the dots
 10.30.d, trig function definitions
 10.30.e, special angles, similar  figure computation
		

• Monday, 10/28 vocabulary

• sinplay   -- just right triangle sine
• cosplay   -- just right triangle cosine
• tanplay   -- just right triangle tangent
• TraceSin   -- drag point f(x) to state and show new ( x, f(x))
• TraceCos   -- drag point f(x) to state and show new ( x, f(x))
• TraceTan   -- just graph with a slideable point to display coordinates
• SinCosTan1stDay   -- Just sine, cosine, tangent of right triangle angles.
• SinCosTan6fx   -- All 6 functions in right triangle only.
• SinCosTanAllNumbers   -- All 6 functions in right triangle and forall numbers,
      * controlled by figure for right triangle,
      * parameter-defined angle measure in degrees for all measures, and
      * parameter-defined angle measure in decimal number times pi for radian measures
• sinNcos.gsp   -- sine and cosine in right triangle only
• 2 Sine Functions -- Asin(Bx-C) + D on 2 functions for comparison also h(x) = sine + cosine
