If is a point on the hyperbola , where is the parameter in its parametric form, then
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
x225-y29=1 is the given hyperbola. Any point on the hyperbola is given by 5secθ,3tanθ Given point on the parabola is Pθ=x1,352,0<θ<π2 i.e. tanθ=52, secθ=32 i.e. x1=152 So, 2x1+9sin2θ=15+9532=20
