Just need some pointers Hi, I know this sounds stupid to ask but could someone tell me what a precis map is, is it one where only one feature is drawn (i.e landuse)?? And also, when giving coordinates, latitude comes before longitude right? thanks

Hi, i am seriously struggling with the following questions: I'm stuck on how I can integrate a second time in question 9. In question 12 I have integrated to find the displacement formula however I'm stuck on how I can substitute pi into the formula. An I'm lost all together in question 13. Any...

Hi, i'm stuck on the following question. If anyone could solve it and show me how you solved it, it would be greatly appreciated :D.

Hi, i'm struggling with finding the derivative for this question and hence finding the equation for the rate of change, any help is greatly appreciated :D.

Hi, im struggleing with these questions: Im completly lost as to how you would do question 7. In question 14 however, I used the quotient rule to derive y=e^x/2 and got e^x/4 however the book lists the derivative as e^x/2 again??? Any help is grealty appreciated.

I'm wondering if anyone can help me with the following questions: In question 5 i get 0 as answer (which is obviously wrong), I think it may have something to do with my integration as when I integrate y=sec^2(x/4) i get y=4tan(x/4)...is this correct? Im lost all together on question 6...

Hi, a struggled with these questions in the excercise: In 1v) the answer was given as cosx/sinx=cotx, im sure this is correct but I have no idea why, could someone please explain to me why that is the answer? In 3 and 4 I am stuck with finding the gradient, i can derive the y value easy enough...

Hi, I have a task coming up soon and I need to relate some changes in the current budget to the economic effects of: -Resource Use -Income Disribution -Economic Activity Im a little stuck and am not sure where my examples fit in. At the moment I have the $19billion investment in education to...

Hi, guys I was doing some revision today and came across these trigonometric results questions and I must have skipped the lesson becuase I have no idea on what I have to do to solve them. Any help on solving the following is greatly appreciated: 4) Simplify the following:

Hi, I need a bit of help with the following question: I tried to solve simultaneously but ended up with r^2-r which I couldn't really use. Any help is greatly appreciated. Thanks.

Hi all, im struggling with finding the volumes and areas in these questions. I have solved part (a) in both of these questions but cannot solve part (b) in both: I made out 53a) to equal ln (5/2) units^2 and 55a) to equal 1.29 units^3 which are both correct according to the answers. However, I...

Hi guys, I am struggling with this question here: I have listed my answer (well as close as I have got to the answer) beneath the question, however it is incorrect according to the book. I used the product rule to first derive the numerator to get the equation, (1+lnx)/e^x. I then used the...

Hello, im struggling with components in these two questions: Im completly unsure of how I would integrate in question 2, the e^x^2 confuses me the most. In question 8 I am stuck on how I would turn y=e^x into x=..., I am fine with the simpsons rule part. As always, any help is greatly...

I am struggling with these two questions: I am unsure of how to integrate e^2y in question 11 and am stuck on the second half of question 12, as in I can show that they equal (x-6)/(x-1) but am struggling when it comes to integrating. Thanks in advance for any help. BTW sorry about the...

Hi guys, i need some more help with logs and deriving them and stuff. Two questions I struggled with are below, I can get the first derivative for question 9 but am unsure of how I would get the second derivative and make it equal zero ect. And i'm completly lost on question 10 as far as making...

Hi, any help with the following questions would be greatly appreciated. BTW, the 1 above the f in question 2a is supposed to indicate the derivative of, not to the power of 1.

Hi, I currently need a UAI min of 85.00 to enter into a BTech degree I want to do at uni. I have read hundreds of articles on this site on how to predict UAI but all seem to confuse me. So I am wondering if you guys can help give a 'ball park' of where I can expect my UAI to be at the moment...

Hi, just wondering if anyone can help me solve this question regarding the practical use of calculus. A 5m length of timber is used to border a triangular garden bed with the other sides of the garden against the house walls. i.e. ___|\ ___|=\ ___|==\ 5m __x|===\ ___|====\ ___|=====\...

Hi, I have two questions here that really puzzled me, they both involve using the Function of a Function Rule with regard to exponential functions, both times I seem to get the incorrect answer so a step-by-step explaination would be greatly appreciated. 1) Differentiate e2x+1/2x+5 2) Find the...

Hi, came across these today and struggled abit with the following questions: 1) Find the volume of the solid of revolution that is formed when the curve y=x^2+2 is rotated about the x-axis from x=0 to x=2. (The x^2 seems to confuse me here) and... 2) Find the volume of the solid formed whe...
