How to convert daily returns to annual returns?

So, let me start with your second question. No you cannot multiply by 365. You could approximate it by $$\log(\text{Annual Return})=365*\log(\text{Daily Return}),$$ but for what you are doing, it ...

How to calculate cost of equity?

Your formula is wrong. The derivation for the cost of equity $r_E$ is actually: $r_A = r_D(1-t)\frac{D}{V}+r_E \frac{E}{V}\\ r_E \frac{E}{V} = r_A - r_D(1-t)\frac{D}{V}\\ r_E = r_A \frac{V}{E} - ...
