Answer 2

To simplify the expression (1 + cosα) / sinα + (1 + cosα) / sinα, you can first find a common denominator and then combine the fractions:

(1 + cosα) / sinα + (1 + cosα) / sinα

Since both fractions have the same denominator (sinα), you can combine them:

[(1 + cosα) + (1 + cosα)] / sinα

Now, combine the numerators:

(1 + cosα + 1 + cosα) / sinα

Combine like terms in the numerator:

(2 + 2cosα) / sinα

Now, you can simplify further:

2(1 + cosα) / sinα

So, the simplified expression is:

2(1 + cosα) / sinα
