Thank you Steamking, and Borek for your responses. I will take your advice Borek and just remember the formulas for sulphate and nitrate, and thank you for the correction of the charge. I forgot to put it in. It's fun to see you again Borek, if I remember correctly you helped me 2 years ago...

Homework Statement Ok, I recently started studying again after a 1.5 year break to pursue other things. I am trying to plow through this chemistry course, and I remember this forum where I basically got through my entire physics course because of the help of this forum which I greatly...

The reason I use "ae" is because my teacher told me to always include it in my calculations. Ye, I realized it was wrong as noted, the second integral that is. I should've left out -3/4x^2 in that one to get the correct answer. Also I know C cancels each other out but my teacher told me...

The integral ∫02(-0.75x^2+3dx) [0.75x^3/3+3x+c]20 = -0.75*2^3/3+3*2+c - (0+c) = 4 +c-c = 4ae(area units) that is the area of the function (or half the function right? since it is x0->x2 and not x-2->x2) Then what I did was, just same thing, calculating he half of the rectangle. So...

A = C-B? What I don't know is how to find the area of the rectangle. I know this is supposed to be super easy as it was one of the easier problems on the exam I had.

Ye, I know it didnt work :s I don't know how to calculate the new area if I just color in the rest of the rectangle. I would know how to calculate the function's area i.e the part I would color in, but the part that is already colored I don't know :s.

It's a "-" sign inbetween the integrals. It gets messed up when I try to write it next to each other

Homework Statement http://imageshack.us/a/img197/305/yhmn.jpg What I want to do is calculate the area of the colored space. As you can see in the picture the function is -0.75x^2+3 for the graph. What I did is since the colored area reaches up to y5 and not y3 I took 2...

I may need to take a serious nap! My problem is the squares. As I said previously, the number of squares that goes vertical and horizontal are the exact same ammount, right? I drew the triangle as you said. I am taking a nap now, I am too lost. Can't think straight. Thanks for the help...

The answer is supposed to be 1700. How are u supposed to get to know the number of squares going up and sideways(along)? Since depending on how you interperpt them they can go either up and sideways? I'm sorry for being slow.

Okay, I get it, or at least some of it. The derivative is of course the angle of that tangent. If I draw a tangent there, I still fail to see how I can solve K'(30). You said count the squares, how exactly does that work? I draw the tangent until it reaches y=0? I really need step for step here.

Omg, of course, how can I miss that. That is just redicilous! Thanks man. About 3. a) I don't know. Am I supposed to draw the derivative functions line? and if so, how do I get the function? I am still lost in this.

Homework Statement Problem 1. Calculate: 2 ∫ 6x^2dx 1 Problem 2. Solve as far as you can(simplify the problem): (x-3)(x+2)/2x-6 Problem 3. The Canadian goose came to sweden in the 1930's. Afterwhich the population of the bird increased. At the same time every year they...

Ye ur right, I am pretty much clueless. Thank you for the link!

Oh, it's energy (Joule). So the answer is in joules and not pa's? (My english is kind of bad so I didn't understand your question at first. Apologies)
