The area of the figure enclosed by the curve y = x2-1 and the straight line x + y = 1 is______ .

The area of the figure enclosed by the curve y = x2-1 and the straight line x + y = 1 is______ .


From y = x2-1 and the line x + y = 1, the intersection points are (- 2,3) and (1,0). Therefore, the area of the closed graph enclosed by y = x2-1 and the line x + y = 1 is s = ∫ 1 − 2 (1-x-x2 + 1) DX = (2x-12x2-13x3) | 1 − 2 = 92



Find the area of closed figure enclosed by curve y ^ 2 = x and straight line x = 1
Come on!
Do it with points!


S=∫(-1,1) (1-y²)dy
=∫(-1,1) 1dy-∫(-1,1) y²dy
=2-2/3
=4/3



Limx * LNX (x tends to positive zero)


=lim lnx/(1/x)
From the law of lobida
=lim (1/x)/(-1/x^2)
=-lim x
=0



Limx tends to 1 LNX / X-1
