Answers (1)

Answer:

            \left ( b \right )\tan^{-1}\frac{3}{4}

Hint:

         Use slop of the tangent m=\tan \theta

Given:

            The curve y^{2}=x and  x^{2}=y^{2}at \left ( 1,1 \right )

Solution:

                

Slope of the tangent to curve

y=x^{2}At \left ( 1,1 \right )is m_{1}=2

Slope of the tangent to the curve

x=y^{2}At  \left ( 1,1 \right )is m_{2}=\frac{1}{2}

Angle between tangents to the curve is \tan \theta =\frac{3}{4}

Or \theta =tan^{-1}\frac{3}{4}
