Finding X & Y Components of Vectors

[Coder74]

Im learning about how to find the x and y components of a vector, but I wanted to verify if I'm on the right track..

Ax=A cos(\theta) <-- solving for x

Ay=A sin(\theta) <-- solving for y

So if a vector is 9.55m long and points in a -48.0 degree direction.

Is it Ay= 9.55 sin(-48.0)=7.3

I get:

$$A_y=9.55\sin\left(-48^{\circ}\right)\text{ m}=-9.55\sin\left(48^{\circ}\right)\text{ m}\approx-7.10\text{ m}$$

Your calculator is in radian mode...and don't forget $\sin(-x)=-\sin(x)$...:D
