Answer 1

Ответ:

Объяснение:

sinA+ctgA*cosA=sinA+cosA*cosA/sinA=(sin²A+cos²A)/sinA=1/sinA.

Answer 2

The expression you provided, "sin(A) + ctg(A) * cos(A)", seems to be a combination of trigonometric functions. However, there is no specific simplification or value I can provide without knowing the value of angle A or more context.

If you have a specific value for angle A, you can plug it in to find the numerical result. Otherwise, if you are looking for a more general expression or identity, please provide more information or clarify your question.
