Yer i knew how to do that part so i didnt bother posting it. Thanks for the help people for the first bit.

P = \frac{1000}{1 + ce^{-1000t}}

Hey, im justy wondering how to do this question, its: In a flock of 1000 chickens, the number P infected with a disease at time t years is given by (ill write the equation using latex) where c is a constant. Show that eventually all of the chickens will be infected.

by using the substitution of x=sin\theta, show \int_{\frac{1}{root 2}}^{\frac{root 3 }{2}}\frac{1-2x^{2}}{x^{5}-x^{3}}dx there we go.

umm do you know how to copy it from the latex thing?

hey, does anybody know how to do this question Its: by using the substitution of x=sin\theta, show \int_{\frac{1}{root 2}}^{\frac{root 3 }{2}}\frac{1-2x^{2}}{x^{5}-x^{3}}dx

hey thanks man, didnt even think of it that why

hey, does anybody know how to do this question: Show that the derivative of y = ln(x-3) - ln(x+3) is given by 6 over x^ - 9 Thanks in advance

i dont have the answer but i seems right. if someone else thinks that it is wrong please post what they think

hey, does anybody know how to derive a^(5x) with rescept to x. thanks in advanced

hey, for the second one i got 0.018 units^2 but i dint know if its right...i did it in that latex thing but i dont know how to put it here and yer they all mean the same thing

h = (2-0)/4 h =1/2 f(0)=0 f(0.5)=-0.25 f(1)= 0 f(1.5)=(0.75) f(2)=2 A= (0.5)/2(0+2(-0.25+0+0.75)+2) A=3/4 units squared Is the second one using trapezoidial rule or just integration You get either one trap question or one simpson rule question in the HSC

hey just wandering what the exercise is and the name of the subheading of the section. i got the 2/3 unit book

Hey, I just got a question about integration on the y-axis. it is: What is the area between the curve x = 1 - (y^2) and the y-axis. i got two thirds but the book says 1 and a third. Thanks in advnce

hey there is two ways you can do this the first way is the way you do it if its a 3 mark question x=0.21666666.... 1000x=216.666666 1000x-x=999x 999x=216.45 x=(216.45)/999 which is also equal to 13/60 the other way is if its only worth 1 mark what you do is get where the number...

im just looking at your sign jetblack and there is a total of 17 units there....why sooo many?

whoops....most stupid mistake

i fixed mine up but it seems that we have got opposite signs

hey, im just wondering if i did this question right. its question 6 (b) if anyone has got the paper and ill write the question underneath for anyone that doesn't have it. here it is: It can be shown that sin3a=3sina-4sin^3a for all values of a. (Do NOt prove this.) Use this result to...
