## Trigonometry - Sin and Cos

Canvas not supported
Drag on the triangle to change its orientation.
Use the sliders to change the angle and the length.
The "Switch Angle" shows how to use the other angle to perform the calculation.

## Vector Components

Canvas not supported
Drag the head of the arrow to see how its components change.

## Vector Decomposition (from angle and magnitude)

Canvas not supported
Drag the head of the arrow to see how its components change.
Click "Switch View" to see different way to visualize the decomposition.

Write out each vector in component form (i.e. with $\hat i$ and $\hat j$) and add them up algebraically to see if it gives the same result.
