I figured out the 1st problem, just need help with 2 and 3b.

My instructor gave me some problems to help study for the quiz on Monday, but i have no idea how to go about solving them.. 1) In martians, Gene 1 is determining eye shape (A-star eyes; a- square eyes) and Gene 2 is coding for presence or absence of tail hairs (B-hairy tail; b-smooth tail)...

What would i do with it? just subtract it from the sin(6t)/t?

Factor out the 1/2?

Would the first one be \frac{1}{2}x_\frac{sin(6t)}{6}? I have in my notes that \int cos(kx)dx= \frac{sin(kx)}{k}+C For the second i have y=\frac{100-12x}{7} so the area would A=\frac{600-72x^{2}}{7} Would i take the derivative of the Area, set the top and bottom to 0 to find the...

1) Find the Indefinite Integral. (1-cos(6t)/2)dt I have the first part: 1t-sin (3t^2) I'm not really sure about the (3t^2) part, then after that I'm lost. 2)A vet has 100ft of fencing to construct 6 dog kennels by building a fence around a rectangular region, and then subdividing into 6...

Ok got it... On the second one I used the chain rule and ended up with: -2(2x-5)^-2 * (12x-30)(x^2-5x)^5 and now I'm stuck yet again.

yeah I've had this it's what's next is what i have the problem on.. cos(3*pi*x/2)(3*pi/2)-sin(3*pi*x/2)(3*pi/2) do i just leave it like that? or should i rearrange the constant to the front.

yeah i wrote it down wrong..

yeah, i know how to do chain rule.. derive outside, leave inside, then derive outside, but since there's it's 3pi(x)/2 would i use the quotient rule or what. I know 3 pi/2 is a constant.

damn..can't believe it was that simple i forgot about it maybe the "factor" was a dead giveaway. So if i applied that to problems 3 & 4 3) y'=-y^2-2xy/x^2+2yx 4) y'=1-2y/2x+2y-1 please tell me i did it right..

sorry math and physics is not my forte i guess the review problem would be y=3x/xz?

thanks..that helps a lot..ok reviewed it 3) y'=-y^2-2xy/x^2*2yx 4) y'=1-2y/2x2y

would the third one be y'=-y^2-2xy/(x^2*2y)for the last one would it be y'= 1-2y/2xy?

Homework Statement I'm supposed to just differentiate these 2 1)http://img132.imageshack.us/img132/8439/img0543hd2.jpg 2)http://img142.imageshack.us/img142/8544/img0544sr0.jpg And use implicit differentiation to fidn dy/dx on these 2...
