what kind of marks do i need in the actual exam, if possible for 99 right now ranks are eng adv 25 mx2 1 mx1 2 eco 9 business 1 school rank around 120

I_{n}=\int_{0}^{\pi }\frac{1-\cos nx}{1-\cos x} \\ I_{n}=\int_{0}^{\pi }\frac{1-(1-2\sin ^{2}\frac{nx}2{})}{1-(1-2\sin ^{2}\frac{x}{2})} \\ =\int_{0}^{\pi }\frac{\sin ^{2}\frac{nx}{2}}{\sin ^{2}\frac{x}{2}} \\ Let\ \theta =\frac{x}{2} result follows not good at writing it

sum x+x^2 +x^3+.... then sum 1+2x+3x^2+.... result should come in a few more steps

sum \frac{1}{5}+\frac{2}{5^2}+\frac{3}{5^3}+....

i was talking about series q

what did you get for answer

considered the series x + 2x^2 +3x^3+.... i also know of another way

1/5+2/5^2+3/5^3 = ?

correct solution but mightve been easier just moving c/2 to the right side evaluate from (0 to pi/4) ∫(1-tanx)/(1+tanx) dx

have you solved it or is that where you got up to

first is easy and ii is 0 given A,B,C are angles in a triangle, show that tan(A/2)tan(B/2)+tan(B/2)tan(C/2)+tan(A/2)tan(C/2) = 1

why is there such a large range of estimates
