Mathematics - 18 October 2007

I really need help understand Trigonometric Identities. Especially simplifying them in terms of sin and cos. Math is like a foreign language to me!! Could I get some tips on how to decipher this stuff?

I’m looking over Derivatives of Sines and Cosines and can’t figure out how to go from step #1 to step #2. The author of my calculus book has a habit of not tell you how he goes from one step to the other. I have the sin/cos identities in front of me and I still can’t figure it out.

Step #1
Lim h-->0 [ (sinxcosh + sinhcosx) – sinx ] / h

Step #2
Lim h-->0 [ (cosx)(sinh/h) – (sinx)(1–cosh/h) ]

how would you solve each equation by FACTORING?
please show steps


5x^2 - 180 = 0


3x^2 - 16x - 12 = 0

3x(x-1) - 3(2x +1) = 0

I am unsure how to do these questions so I will pick one from each section to see how to do them please help.

value of h- each says the same thing which is For each of the folowing, draw a rough graph of y=x^2 and the given function to thow their relatonship.

1.y=(x+5)^2

2. Value of k. y+2=x^2


3. The last section on this practice sheet says for each of the following
- describe the graph in relation to the basic quadratic function y=x^2
-draw a rough graph, including the basic function

(y-2)= (Y+3)^2

I understand the "or" statements, but I'm not sure if I'm supposed to do the whole thing with switching the inequality sign and changing the number at one side of the inequality to a negative. I have a test tomorrow and still don't understand. Can anybody explain to me what to do?
