1.sqrt(4-x^(2))

Integrate the function is exercise. sqrt(4-x^(2))

The tangent at a point P on the curve y =ln ((2+ sqrt(4-x ^(2)))/(2- sqrt(4-x ^(2))))-sqrt(4-x ^(2)) meets the y-axis at T, then PT^(2) equals to :

The tangent at a point P on the curve y =ln ((2+ sqrt(4-x ^(2)))/(2- sqrt(4-x ^(2))))-sqrt(4-x ^(2)) meets the y-axis at T, then PT^(2) equals to :

The domain of sqrt(4-x^(2)) is

Lt_(x to 2) sqrt(4-x^(2))=

Domain of sqrt((4-x^(2))/([x]+2))

Find the domain of f(x)=sqrt((4-x^(2))/([x]+2))

If f(x)="sin ln" (sqrt(4-x^(2)))/(1-x), then
