![### Unit-Vector Notation for Given Vectors
Given the vectors below, all with magnitudes of 41.5, determine their unit-vector notations.
(a) **Vector \(\vec{E}\)** with a direction of 75.0° counterclockwise from the +x-axis.
\[
\vec{E} =
\]
(b) **Vector \(\vec{F}\)** with a direction of 75.0° counterclockwise from the +y-axis.
\[
\vec{F} =
\]
(c) **Vector \(\vec{G}\)** with a direction of 75.0° clockwise from the −y-axis.
\[
\vec{G} =
\]
#### Explanation:
1. **For Vector \(\vec{E}\)**: To find the unit vector notation, decompose it into its x and y components using the given angle and magnitude.
2. **For Vector \(\vec{F}\)**: Similarly, decompose this vector into components, noting the direction relative to the +y-axis.
3. **For Vector \(\vec{G}\)**: Again, decompose this vector into components, noting that the angle is measured clockwise from the −y-axis.
