What is the derivative of y=tan(arcsin(x))?
Anuta_ua [19.1K]
Hello,

(tg(x))'=1/cos²(x)

(arcsin(x))'=1/√(1-x²)

cos²(arcsin(x))=1-sin²(arcsin(x))=1-x²


(tg(arcsin(x)))'= \dfrac{1}{cos(arcsin(x)))^2} * \dfrac{1}{\sqrt{1-x^2}} \\&#10;&#10;=\dfrac{1}{1-sin(arcsin(x))^2}* \dfrac{1}{\sqrt{1-x^2}} \\&#10;&#10;= \dfrac{1}{1-x^2} * \dfrac{1}{\sqrt{1-x^2}} \\&#10;&#10;\boxed{= \dfrac{\sqrt{1-x^2}}{x^4-2x^2+1}}\\&#10;&#10;

Total = Small + Big

This gives

Total = p + 20
