Q1)
You have to find the coff of x in expansion of ((x + (2/x^2))

so when you expand it by formula i.e a^n + (nC1)(a^(n-1))(b)+.......
You will find coff of x when you reach at (7C2)(x^(5))((2/x^2))^(2) than solve it you get coff of x as 84

Q2)
Given ; dv/dt=50, dv/dr = (4pi(10)^2) <-- diff. of volum of sphere, and we have to find dr/dt
so, dr/dt = dr/dv * dv/dt ; here dr/dv = 1/400pi, so dr/dt = 1/400pi * 50 = 50/400pi = 1/8pi

Q3)


ii)
pi is constant and integrate (x-2)^4 ; formula is pi integration of y^2
so multiply pi with [((x-2)^(5)/5)] limit is 0 to 2
hence solve the equation, you get is 6.4pi.

Which type of functions you need to sketch ?

Q10 part two how to sketch the two graphs

for f(x) It is linear, put x as 0,1,2,3 and get values of y, plot it on graph paper.
for f inverse, reverse the coordinates, example, you got x = 0 and y = -5 from f(x) so here, it will be x = -5 and y = 0 .. and so on, plot it

Q2 part 1 how to expand in descending powers of x

Follow the formula from booklet, and expand the bracket till first three terms,
so it will be ;
(2x)^5 + (5C1)(2x)^(4)(-3/x)+(5c2)(2x)^(3)(-3/x)^(2) so solving this expression you get is 32x^5 - 240x^3 + 720x
