do i have to memorise all of themHe's right. It's the same as the one I've written
he also wrote sin360+x=sinx
cos360+x=cosx
tan360+x=tanx

I don't about the 360+x ones sorrydo i have to memorise all of them
he also wrote sin360+x=sinx

thank youy = a/x = a x^-1
the volume is given by integrating πy^2. Here y is the equation of the line.
We're given Volume when rotated about x-axis is 24π.
24π = ∫ π (a * x^-1)^2 dx
24π = ∫ π (a^2 * x^-2) dx
24π = a^2 π ∫ (x^-2) dx
24 = a ^2 ∫ (x^-2) dx
Now integrate and put the limits:
24 = a^2 (1/3 - 1/1)
solve it to get:
a^2 = 36
=> a = 6 Ans.
thanks dear but in the marksheme its 88It can't be 88.2 cm! it's 33 cm.
9(ii) please with all steps. In part (i) the partial fractions are A=6, and Bx+C (B=-2)(C=1)
In Q.10 i need help in finding Alpha and Beta angles. Got P and Q. View attachment 60356
Buddy why didnt u multiply 6 with the first term binominal expansion?View attachment 60361
not clearly coz no appropriate things to write on m enjoying vacations xD
coz 6 is in numerator. so 6(denominator)^-1Buddy why didnt u multiply 6 with the first term binominal expansion?
I dont think u cant completely ignore numerator.coz 6 is in numerator. so 6(denominator)^-1
Sorry?I dont think u cant completely ignore numerator.
6 is in numerator and u didnt multiply it after u expanded them?Sorry?
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
