										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

TRIANGE ABC IF ANGLE A =X,ANGLE B=3x-2AND ANGLE C=Y AND ANGLE C- ANGLE B=9.FIND THREE ANGLES

Hint, Using the conditionANGLE C- ANGLE B=9, we can find that angle C = 7 + 3x. So the three angles in terms of x will be A = x and B = 3x-2 and C = 7 + 3x. Thanks

can anyone please show me how to find sum of coefficients in expansion (x+2y+2)^10

The put the values of x & y as 1 and you will get the answer as 5 10 .

 Sourabh Singh 14 days ago

but x=y=1 after writing complete expansion so 3^10 will come Thanks

 Nishant Vora 14 days ago

if you have put the values in x=y=1 in your equation u willget 5^10 so that the final answer is 5^10 thank you boss
