This past week you should have been continued
your exploration of analytic trigonometry. Sum and Difference identities
are useful in simplifying expressions and double angle identities are helpful
with word problems.
Just a quick check-
·
Are you accumulating a list of all identities
for easy reference?
·
Can you use sum and difference identities to
simplify expressions?
·
Are you able to use a double angle identity to
simplify an expression?
·
Did you realize that co-function identities relate
sine to cosine and tangent to cotangent?
·
Can you use a power reducing identity to
eliminate powers from an expression?
·
Are you able to apply half angles to solve
trigonometric equations?
For week 13 you will be looking at applications of trigonometry
including the law of sines and cosines, and an introduction to vectors
