y = cos ^(-1)((1 - x^(2))/(1+ x^(2))) 0 lt x lt 1
Text Solution
|
y = sin ^(-1)((1 - x^(2))/(1+ x^(2))) 0 lt x lt 1
Text Solution
|
Find the derivatives of "cos"^(-1)(1-x^(2))/(1+x^(2)) (0 lt x lt 1)
Text Solution
|
y = cos^(-1)((1-x^2)/(1+x^2)), 0 lt x lt 1.
Text Solution
|
y = sin^(-1)((1-x^2)/(1+x^2)), 0 lt x lt 1.
Text Solution
|
