Hi guys, I want to write up some math and have the following code:
\begin{align}
L_{A}(s)&=V(A,0)-V(A,s) \\
&=\int_{t=A}^{T(A)+A-\alpha S_{A}}e^{-r(t-A)}W_{t}dt - \int_{t=A}^{T(A)+A-\alpha (S_{A}+s)}e^{-r(t-A)}W_{t}dt \\
&=\int^{T(A)+A-\alpha...
Hi, everyone, I'm new here and don't know how to type mathematics, but I have a scanner.
I have a function L_A and it is an integral. I want to differentiate this function with respect to A. I already have the answer written but what I don't know is how it was obtained.
Just by...
