(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Find limit as (r, θ)----> (0, pi/2) for the function:

r= (w secθ)/(secθ+tanθ)^(Vs/Vr)

Both w and Vs/Vr are constants in this question

3. The attempt at a solution

I tried with L'hopital but it didnt turn well as when I differentiate secθ, I got ln (secθ + tan θ)

which when θ approaches 0 still gives me infinite..

Please help me....

I've tried so long to get the answer, but nothing seems to work and I have to pass this up tommorow.
