mω²acosθ = mgsinθ
ω = √ (gtanθ/a)
y = 4cx²
tanθ = dy/dx = 8xC
(tanθ)? , b = 8aC
ω = √ (g×8aC/a) = 2√ (2gC)

- Let t? denotes r+1th term of (? x? +? x? )¹?
t? = ¹? C? (? x? )¹? (? x? )? = ¹? C? ¹? x? ¹?
If t? is independent of x
90-15r=0? r=6
This differs from the solution.
Let's follow the solution's powers.
(10-r)/9 - r/6 = 0? r=4
maximum value of t? is 10K (given)
? ¹? C? is maximum
By AM? GM (for positive numbers)
(? ³/2+? ³/2+? ²/2+? ²/2)/4? (? /16)¹/?
? ? ? 16
So, 10K = ¹? C?16
? K=336

Circle x²+y²-2x-4y+4=0
⇒ (x-1)²+ (y-2)²=1
Centre: (1,2) radius=1
line 3x+4y-k=0 intersects the circle at two distinct points.
⇒ distance of centre from the line < radius
⇒ |3×1+4×2-k|/√ (3²+4²) < 1
⇒ |11-k|<5
⇒ 6
Number of K is 9.

lim (x→1) (x+x²+.+x? -n)/ (x-1) = 820
⇒ lim (x→1) (x-1)/ (x-1)+ (x²-1)/ (x-1)+.+ (x? -1)/ (x-1) = 820
⇒ 1+2+.+n = 820
⇒ n (n+1)=2×820
⇒ n (n+1)=40×41
Since n∈N, so n=40

|a|=|b|=|c|=1
|a-b|²+|a-c|²=8
⇒|a|²+|b|²-2a.b+|a|²+|c|²-2a.c=8
⇒4-2 (a.b+a.c)=8
⇒a.b+a.c=-2
|a+2b|²+|a+2c|²
=|a|²+4|b|²+4a.b+|a|²+4|c|²+4a.c
=10+4 (a.b+a.c)
=10-8=2

Kindly consider the following figure
|x|<1, |y|<1, x? y
(x+y) + (x²+xy+y²) + (x³+x²y+xy²+y³) + .
By multiplying and dividing by x-y:
(x²-y²)+ (x³-y³)+ (x? -y? )+.)/ (x-y)
= (x²+x³+x? +.)- (y²+y³+y? +.)/ (x-y)
= (x²/ (1-x)- (y²/ (1-y)/ (x-y)
= (x²-y²-xy (x-y)/ (1-x) (1-y) (x-y)
= (x+y-xy)/ (1-x) (1-y)
