" 7."x sin^(-1)x

Integrate the functions (1.)(sec)^2(7-4x) (2.) sin^(-1)x/sqrt(1-x^2)

Integrate the functions (1.)(sec)^(2)(7-4x) (2.) (sin^(-1)x)/(sqrt(1-x^(2)))

If y = sin (7 Sin ^(-1) x) then (1-x ^(2)) y _(2) - xy _(1)=

If "cos"^(-1)x+"cos"^(-1)y=(2pi)/(7) , then the value of "sin"^(-1)x+"sin"^(-1)y is

cos ^ (7) x + sin ^ (4) x = 1
