Answer 2

The expression you've provided is a combination of trigonometric functions. Let's simplify it step by step:

Expression: (sina/1+cosa) + (1+cosa/sina)

Step 1: Distribute the terms in the first part of the expression. (sina/1) + (sina/cosa)

Step 2: Simplify each term. sina + (sina/cosa)

Step 3: Common denominator for the second term. (sina * cosa + sina) / cosa

Step 4: Combine the terms over a common denominator. (sina * cosa + sina + sina) / cosa

Step 5: Simplify the numerator. (sina * (cosa + 1) + sina) / cosa

Step 6: Factor out sina from the numerator. sina * (cosa + 1 + 1) / cosa

Step 7: Simplify further. 2 * sina / cosa

This is the simplified expression: 2 * sina / cosa

Please note that this is a simplified form of the expression based on basic trigonometric identities. If you have specific values for the angles or want to evaluate it further, you can substitute numerical values for sina and cosa.
