2. ### Chain Rule Help

alright - so when i find the derivative of cos(w-1) - it will be -sin(1) - making the equation -sin(1)/cos(w-1), making -sin/cos = -tan(w-1) the answer thanks for all your guys help - much appreciated
3. ### Chain Rule Help

if i have \frac{d}{dx} \ln u = \frac{1}{u} then i find d/dx cos(w-1) = -sin(1) then plug that into the u? so 1/-sin(1) - then im stuck
4. ### Chain Rule Help

the u would be the cos(w-1) right ?
5. ### Chain Rule Help

see thats where im confused.....i believe i have to use the chain rule twice....but im just confused on where to start and how to integrate in the ln
6. ### Chain Rule Help

well the derivative of (ln x) is 1/x

13. ### Quick derivative

i am having trouble with a fairly easy derivative - and was wondering if someone could show me the steps how to find this? Find this derivative algebraically f(x) = x^3 (x cubed) at x= -2 The answer in the back of the book says the derivative is 12 - but I did the work and got 4. Please...
14. ### Trig Help - Need Help Verifying This Identity!

hmm - can you simplify any of it for me in steps?
15. ### Trig Help - Need Help Verifying This Identity!

im trying to verify this identity - sin x + tan x / 1 + cos x = tan x - i get lost very easily and need the steps - can anyone help me? :yuck:
