You can even make a quick sketch of the graphy. Thats what I did. Then it was clear that 4 and 0 are the required limits -

*joins* That was funnnn. No? :LOL::LOL: -
Mathematics: Post your doubts here!
Your concepts are clear. No doubt. Since you know integration. In this question you are not given the limits but youre told that you have to find the area in the first quadrant. This suggests that there is no negative limit. So if you plug in a few values of x in the equation you will get x as 4... -

can u tell me the answer.? :p im getting 42.67 for the first part. and 0.5 for the second :p -

I know everything about integration but ive never seen 'vertical or horizontal elements' in any of the questions :p My bad :p I tried solving your question. Using u substitution. I got the integral but what next? Couldnt figure out the limits so yeahhh :p -

(x^2 + y^2) = 2(x^2 – y^2) Co-ordinates of M ( maximum point) Solve the square. And the parenthesis. x^4 +2(x^2)(y^2) + y^4 = 2(x^2) – (2y^2) Differentiate. Dy/dx , 4(x^3) + 2[2*x*(y^2) +2*y*(x^2) (dy/dx)] +4(y^3)(dy/dx) = 4x – 4y(dy/dx) 4(x^3) + 4*x*(y^2) + 4*y*(x^2)(dy/dx)... -

ii)Take 2 out. 2 ʃ ((2-u)^2 / u) du Solve the square. 2 ʃ (4 - 4u +u^2)/u Make fractions. 2 ʃ 4/u – 4u/u + u^2 /u) Cancelling out will give you. 2 ʃ 4/u – 4 + u Now integrate. 2 [ 4ln IuI – 4u + u^2/2 ] 8ln IuI - 8u + u^2 Plug in the limits. (8ln I2I – 8(2) + (2^2)) – (8ln I1I –... -
