Question

Sina+tga/1+Costa упростите пожалуйста если что чёрта это дробь

Answer 1

Ответ:

$tg\alpha$

Объяснение:

$\displaystyle \frac{sin\alpha+tg\alpha}{1+cos\alpha} =\frac{sin\alpha^{(cos\alpha}+\frac{sin\alpha}{cos\alpha} }{1+cos\alpha} =\frac{\frac{cos\alpha sin\alpha+sin\alpha}{cos\alpha} }{1+cos\alpha} =\frac{sin\alpha(cos\alpha+1)}{cos\alpha} \div(1+cos\alpha)=\frac{sin\alpha(cos\alpha+1)}{cos\alpha} *\frac{1}{cos\alpha+1} =\frac{sin\alpha}{cos\alpha} =tg\alpha$

______________

формула:

$\bf \displaystyle tg\alpha=\frac{sin\alpha}{cos\alpha}$

Understanding the Fraction Sina tga/1 Costa

The expression "Sina tga/1 Costa" appears to be a combination of words and symbols that may not form a standard mathematical expression. However, if we interpret it as a fraction, we can break it down as follows:

- Sina: This could be a variable or a placeholder. - tga: This might be a misspelling of "tan" which stands for tangent in trigonometry. - 1 Costa: This part is unclear and doesn't seem to correspond to a standard mathematical term.

Given the unclear nature of the expression, it's difficult to provide a precise mathematical interpretation without further context or clarification. If there's a specific mathematical concept or expression you're referring to, please provide additional details so that I can assist you more effectively.
