If ⁻¹ ( y b )=n ( x n ) , then
Options
- Ax y₁=n b²-y²
- Bx y₁+n b²-y² =0
- Cy₁=x b²-y²
- Dx y₁- b²-y² =0
Correct answer
B. x y₁+n b²-y² =0
Step-by-step solution
Given, ⁻¹ ( y b )=n ( x n ) ( y₁= d y d x ) Differentiating w.r.t. ' x ' gathered - 1 1-(y / b)² y₁ b =n 1 (x / n) 1 n - b b²-y² y₁ b = n² x 1 n - y₁ b²-y² = n x -x y₁=n b²-y² x y₁+n b²-y² =0 gathered
