Question: Is the value of sin 30?

What is the formula for sin 30?

Sin 30 Formula: Sin 30 degrees is equal to cos 60 degrees. The value of sin 30 degrees is 1/2.

What is special about the sine of 30?

Because this works for all right triangles, no matter the size, with an angle of 30 degrees, then, without naming the triangle, we can say sin30 = 0.5. The same method was used originally to get the trig function values for any angle, and this was used to make tables.
