pi/2 to -pi/2 ∫ sqrt (cosx – cos 3x) dx = – [-pi/2 to pi/2 ∫ sqrt (cosx – cos 3x) dx] Since the function sqrt (cos x – cos 3x) is an even function, the difinite integral is equal to = – 2[ 0 to pi/2 ∫...

Property: If m & M are the minimum and maximum values of f(x) in [a, b], then ∫ f( x) between the limits a & b lies between m(b – a ) & M(b – a) 0 ≤ f ’ (t) ≤ 1 for –1 ≤ t ≤ 0 =>f (t) = ∫ f ‘ (t)...
On differentiating w.r.t n & equating to 0, we get (n 3 + 200) * 2n – n 2 * (3n 2 ) = 0 => n 3 = 400 => n = 7.3 Since n is a naturanl no, on verification we can find that a n attains maximum value at...
f(x) = tan(x+ π/6)/tanx = (tanx + 1/sqrt(3)/(1 – tanx/sqrt(3)) * 1/tanx = [sqrt(3) * tanx + 1 ]/[(sqrt(3) – 1) * tanx] The extreme points of f(x) are for f ’ (x) = 0 By differenetiationg w.r.t x and...
The extreme points are attained at f ’(x) = 0 => 6x 2 – 18ax + 12a 2 = 0 => x = 2a, a f ’’(x) = 12x – 18a f ’’(x) 0 if x = 2a Hence the min at x = 2a = x 1 & max at x = a = x 2 The condition that x 1...
Ans: Hello Student, Please find answer to your question below [sint] is a periodic with a period of 2pi.
Ans: Hello Student, Please find answer to your question below [sint] is a periodi with a period of 2pi.
Ans: Hello Student, Please find answer to your question below Since 2n-1 > 0 So x = a is neither maximum nor minimum.
