Intersection Points 02Ab15
1. **Problem Statement:** Find the points of intersection of the curves $y = x^3$ and $x = y^2$.
2. **Step 1: Express both equations clearly:**
- Curve 1: $y = x^3$
- Curve 2: $x = y^2$
3. **Step 2: Substitute $y$ from Curve 1 into Curve 2:**
Since $y = x^3$, then $x = (x^3)^2 = x^6$.
4. **Step 3: Solve for $x$:**
$$x = x^6 \implies x^6 - x = 0 \implies x(x^5 - 1) = 0$$
5. **Step 4: Find roots:**
- $x = 0$
- $x^5 = 1 \implies x = 1$
6. **Step 5: Find corresponding $y$ values:**
- For $x=0$, $y = 0^3 = 0$
- For $x=1$, $y = 1^3 = 1$
7. **Step 6: Points of intersection:**
$$ (0,0) \text{ and } (1,1) $$
8. **Step 7: Sketch and representative strip:**
- The curves intersect at $(0,0)$ and $(1,1)$.
- The area bounded lies between these points.
- The representative strip is vertical (along $x$), between the curves $y = x^3$ (lower) and $y = \sqrt{x}$ (since $x = y^2 \Rightarrow y = \sqrt{x}$) (upper).
**Final answer:** Points of intersection are $$ (0,0) \text{ and } (1,1) $$.
