answer in simplest radical form. sin 90 degrees
To find the simplest radical form of sin 90 degrees, we first need to understand that 90 degrees is equal to π/2 radians.
The sine function (sin(x)) represents the ratio of the length of the side opposite to an angle in a right triangle to the hypotenuse. In a 90-degree angle, the hypotenuse is the longest side and is equal to 1 unit.
Now, let's calculate the sine of π/2 radians using a scientific calculator or a trigonometric table. The sine of π/2 is equal to 1.
Therefore, the simplest radical form of sin 90 degrees is just 1.
sin 90 = 1
