Ans:
Using the inequality
$m(b-a)\leq \int_{a}^{b}f(x)dx\leq M(b-a)$
$a = \pi , b = 3\pi$
$m\leq f(x)\leq M$
Max. value of A
$2\pi M$
Min. value of A
$2\pi m$
You can easily find the m & M from f(x) (I am not finding b/c f(x) is not clear)

Q . LET F 1 AND F 2 ARE THE FOCI OF THE ELLIPSE - 4x 2 + 9y 2 = 36 AND ‘P’ IS A POINT ON THE ELIPSE SUCH THAT - PF 1 = 2PF 2 , THEN THE AREA OF THE TRIANGLE PF 1 F 2 IS ?

Ans: Hello Student, Please find answer to your question below 4x 2 + 9y 2 = 36 By the definition of ellipse, PF 1 + PF 2 = 2a a = 3 PF 1 + PF 2 = 6 PF 1 = 2PF 2 PF 2 = 2 PF 1 = 4 F 1 F 2 can...

if cosx+cosy+cosz=sinx+siny+sinz=0 then prove that sin2x+sin2y+sin2z=cos2x+cos2y+cos2z=0

hello student,, cosx + cosy = -cosz , cos^2x + cos^2y + 2cosx.cosy = cos^2z , in a similar way : sin^2x+sin^2y+2sinx.siny = sin^2z , add eqns & simplify : 1+1+2(cosx.cosy+sinx.siny) = 1...
