Calculation of sina and 90°

To calculate the value of sina and 90°, we need to understand the context in which these values are given. Unfortunately, the provided information is incomplete and does not specify the exact calculation or equation involving sina and 90°.

However, I can provide some general information about sina and 90°.

- sina: In trigonometry, sina represents the sine function, which is a mathematical function that relates the angles of a right triangle to the ratio of the length of the side opposite the angle to the length of the hypotenuse. The sine function is commonly denoted as sin(x), where x is the angle in radians or degrees.

- 90°: This is a specific angle measurement, where 90° represents a right angle. A right angle is formed when two lines or sides intersect and create two equal angles, each measuring 90 degrees.

If you provide more specific information or context about the calculation involving sina and 90°, I would be happy to assist you further.
