Why does sin(35°) equal both a side ratio and a y-coordinate?

[christian0710]

Hi when we look at the function

Sin(35) = opposite/ hypotenus

I know i can find the opposite side by
Sin(35 degree) * hypotenus

But the value of sin(35 degree) = 0,6293 so my question is this:

The sine function tells us that if we divide opposite side by hypotenus the ratio is 0.6292:1
But if we take the sine function to 35 degree Sin(35) does this then tell us "that the sine to 35 degree in the unit circle gives us a value on the y-axis of 0.6292?)

So the sine function can visualized in terms of 1) relationships between sides and 2) the y-value reading of an angle in a unit circle?

Is this correctly understood?

Yes.
