int_(0)^(2)sqrt(2x-x^(2))dx

I=int_(0)^(2)x sqrt(4-x^(2))dx

Find the Sum of number of functions & from the set A={0,1,2} into the set B={0,1,2,3,4,5,6,7} & each that f(i)<=f(j) for i

int_(0)^(a)sqrt(a^(2)-x^(2))dx=

int sqrt(2ax-x^(2))dx

int_(0)^(a)(dx)/(sqrt(ax-x^(2)))

int_(0)^(a)dx/(sqrt(a^2-x^2))

int_(0)^(sqrt(2))sqrt(2-x^(2))dx=?
