Answer 2

It seems like you've entered a combination of mathematical and non-mathematical symbols that don't form a coherent question or statement.

• "sina" appears to be a typo; it should be "sin," which represents the sine trigonometric function.
• "cosa" appears to be a typo as well; it should be "cos," which represents the cosine trigonometric function.
• "tga" appears to be a typo; it should be "tan," which represents the tangent trigonometric function.
