Hi when we are doing sin(value) is this multiplying the value by sin?

NO!!!

If we are given something like this:

sin (pi/ 3)

We are looking for the sine of an angle with a radian measure of pi/3 [60 degrees]

So

sin (pi/3) = √3 / 2

Say i am doing sin(106degrees) how would i explain what I am doing? Need to write it out and don't want to write "do sin"

If the question was:

x = sin(106º)

It reads: "x equals the sine of one hundred six degrees."

Then you could say, "To solve for x, take the sine of one hundred six degrees."
