This is one of the more easier volumes questions (cylindrical shells) but I'm still confused about what I have to find and also the dimensions of the strip or whatever.. So here it is: Q. By taking strips parallel to the axis of rotation, use the method of cylindrical shells to find the volume...

Assume that the probability that a child is female is 1/2, and that sex is independent from child to child. Giving your answers are fractions in simplest form, find the probability that in a family of five children: b. There are two girls and three boys Well I'm going to show my working just...

Sorry it's in a link, not sure how to post it up without one D: The problem I am having with is Q.ii. I used the definition of the ellipse where the distance from the point P to a fixed point over the distance from point P to a fixed line has the ratio of e. Again I am probably wrong, since...

Q. If around 2-3 people are much better than the majority of the cohort, in this case Standard English, will they still be dragged down? Or is that only for first place?

Alright guys, we're only sticking with one topic at a time ie. One thread for MAB, another for BOL and vice versa. So basically, each person will post a question after they have answered a question from the previous post. These questions SHOULD be taken from past papers or trial papers, but some...

^ . I am only up to section 1 of Blueprint for Life! D: /life

I have found out the values for the fraction so here it is: \frac{x}{(x+3)(x-1)}=\frac{3}{4(x+3)} + \frac{1}{4(x-1)} Integrate \frac{x}{(x+3)(x-1)}dx I am partially (lame pun >.>) confused with integrating \frac{3}{4(x+3)} because I don't know what value to multiply the fraction by when...

Okay, so rather than me making several threads with different questions, I'm compiling my questions into one place. 17. If 6PR =120, find the value of r. 14. How many even numbers of 4 digits can be formed with the figures 3, 4, 7, 8. a. If no figure is repeated. b. If repetitions are allowed...

Simplify leaving answers in exact values(\frac{1-cos(\frac{pi}{7})+isin\frac{pi}{7}}{1-cos\frac{pi}{7}-isin\frac{pi}{7}})^7 I do not understand the solution in Terry Lee so thank you in advance.

Q. {(x+1)^2}/8 + {(y-3)^2}/4 = 1 Find the foci and directrices. I dont understand how they got the foci.

Hello my friends. I have been thinking on consolidating all the work I've done so far, but I don't know how to manage the time to do it. I have to do tutor homework as well as write up new notes as I progress through each school day. Does anyone have any suggestions? I can't manage my time well...

Hello. How do we differentiate: Cos(ln(x))?

As above, mine is 37 but im planning to shorten some parts of it or develop a concise series of notes.

Q. Sketch arg(z-i)-arg(z+i) = pi/2How do we do this? Terry lee doesnt explain too well.

Now I've been looking around reliable websites and also through textbooks but 50% say they are organic compounds but the others say they are inorganic compounds. This is also the case with both my PDHPE textbooks :/ Referring to the title, does anyone know for sure which one it is?

Question: (Note I've done the first part) 10.a. Prove that the points on an Argand diagram which represent the complex numbers z_{1}, z_{2} and \frac{z_{1}-ikz_2}{1-ik} where k is a real number, form the vertices of a right angled triangle. You may assume the right angle is at the point...
