										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)Thanks & RegardsJitender SinghIIT DelhiaskIITians Faculty

∫1+tanxtan(x+a)dx

We know that, tan(c-b) = (tan c – tan b)/(1+tan c * tan b), So, (1+tan c * tan b) = (tan c – tan b) / tan (c-b), Put c= x+a, b=x, (1+tanx * tan(x+a)) = (tan(x+a) – tan x) / tan(x+a-x)...

if AB=A and BA=B then which is correct a) A^2=A b) B^2=B c)A=I d) B=I? chapter matrices

Both options (a) and (b) are correct .A 2 =A & B 2 =B.

Look options a) and b) are correct showing that options c and d are also correct.see below for explaination. A 2 =A--------->A.A=A------------->A=A -1 .A(taking one of the A to right side...

Nikhil Upadhyay but why C and D not correct??? if we multiply both side by A inverse.... we will get A=I. ???
