Question

if x= Φ -1/Φ
y= Φ+1/Φ
then find dy/dx​

Answer 1

hope this helps you......

Answer 2

Step-by-step explanation:

=> x = Φ - 1/Φ

=> dx/dΦ = d(Φ)/dΦ - d/dΦ(1/Φ)

=> dx/dΦ = 1 + 1/Φ²

=> y = Φ + 1/Φ

=> dy/dΦ = 1 - 1/Φ²

=> (dy/dΦ) / (dx/dΦ)

=> ( 1 + 1/Φ²) / ( 1 - 1/Φ²)

=> ( (Φ²+1)/Φ²) / ( (Φ²-1)/Φ²)

=> (Φ²+1)/(Φ²-1)
