Ana,

the topics for the Maths Finals are the following:

Like a Star @ heaven law of sine (Sin A / a = Sin B / b = Sin C / c ) to solve triangles' sides and/or angles

Like a Star @ heaven law of cosine ( Cos C = a2 + b2 -c2 / 2ab) to solve triangles too.

Like a Star @ heaven unit circle (All Students Take Calculus!)

Like a Star @ heaven how to find an angle, when given the area (K)
K = 1/2 ab sin C

Like a Star @ heaven cosine/since waves excercises (from a graph, draw an equation ... )

Good preparation for everyone !

In addition to Oscar's review,

Remember to study the simple sin/cos equations such as:

SInX = -.4
Arcsin(.4) =X
X= 23.6 (First Quadrant, now change to negative, third and fourth quadrant!)

Hope it helps!

C²=a²+b²-2absinc

This is the other Law of Cosine!

Happy Finals Razz
