Example: Symbolic Solving with Find

Solve Blocks > Example: Symbolic Solving with Find

Find the intersection of two circles symbolically.

1. Set the initial conditions in a solve block.

2. Use the find function to find the intersection point of the circles.

3. Define a new variable that represents the intersection point of the circles.

4. Use the variable M outside the solve block.

5. Evaluate numerical results using the keyword float.
