Can you help me find the first and second derviative for xsquare root 4-x^2. FOr the first one I got -2x^2-4/square root 4-x^2. And for the second derviative I got -4(4-x^2)^1/2x+(2x^3-4x)(1/(4-x^2)^1/2) over 4-x^2

Question

Can u let me know if they are correct if they arent what are they,

not quite. The 1st derivative is (-2x^2+4)/√(4-x^2) The 2nd derivative is (2x^3-12x)/(4-x^2)^{^3/2}
