The angle between the curves `y^2=x` and `x^2=y` at `(1,\ 1)` is `tan^(-1)4/3` (b) `tan^(-1)3/4` (c) `90o` (d) `45o`

Text Solution

Verified by Experts

Slope of tangent to curve `y=x^2 `at (1,1) is `m_1​=2`
Slope of tangent to curve `x=y^2` at (1,1) is `m_2​=1/2`
​ Angle between tangent to the curves is
`tanθ=3/4`
​ or `θ=tan^(−1)(3/4)`​
