- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
Given, Equation of hyperbola x2-y2=1 Now parametric point is given by asecθ,btanθ≡2,1 as given θ=45° & a=b=1 Now finding slope of tangent at the given point by differentiating the curve we get, 2x-2ydydx=0 ⇒dydx2,1=21 So, slope of…
