    Show geometrically why \[ \int\limits_{1}^{0}\sqrt{2-x ^{2}}dx\] = (pi/4)+(1/2)

    You have to break the area under y=sqrt(2-x^2) into two peices a circle and and a triangle

    yup so. the first part is the sector of a circle (1/4)(area of the circle) + the second part which is the triangle from sqrt(2) to 1.

    area = pi * r^2 = pi(2) than divide by the angle/360 THAN add on the additional triangle :P
