Flashcard 1: How do you sketch a slope field for dy/dx=ydy/dx = ydy/dx=y?

Answer: Compute m=ym = ym=y at grid points. Evaluate yyy at each grid point for slope.

Flashcard 2: What information can you obtain from a slope field?

Answer: The general shape and behavior of solution curves. Reveals overall patterns and equilibrium points.

Flashcard 3: What is a key feature of slope fields for dy/dx=y/xdy/dx = y/xdy/dx=y/x?

Answer: Lines are radial from the origin. Lines point away from origin along rays.

Flashcard 4: How is a slope field constructed for dy/dx=x+ydy/dx = x + ydy/dx=x+y?

Answer: Compute slopes at grid points using m=x+ym = x + ym=x+y. Substitute coordinates into the differential equation.

Flashcard 5: What does it mean for a slope field to have symmetry?

Answer: The slope pattern repeats across an axis. Pattern mirrors across coordinate axes.

Flashcard 6: What effect does a positive slope have on a slope field?

Answer: Lines tilt upward from left to right. Positive slope creates upward-slanting segments.

Flashcard 7: What does each line segment in a slope field represent?

Answer: The slope of the solution curve at a given point. Each segment shows the tangent direction at that point.

Flashcard 8: How is dy/dx=0dy/dx = 0dy/dx=0 represented in a slope field?

Answer: Horizontal line segments. Zero slope creates flat line segments.

Flashcard 9: How do you determine equilibrium solutions from a slope field?

Answer: Look for horizontal line segments. Zero slope indicates equilibrium solutions.

Flashcard 10: What is the slope at (2,0)(2, 0)(2,0) for dy/dx=1ydy/dx = \frac{1}{y}dy/dx=y1​?

Answer: Slope is undefined. Division by zero creates undefined slope.

Flashcard 11: How do you find the slope at (x,y)(x, y)(x,y) for dy/dx=x2+y2dy/dx = x^2 + y^2dy/dx=x2+y2?

Answer: Compute x2+y2x^2 + y^2x2+y2 at (x,y)(x, y)(x,y). Evaluate the expression at each grid point.

Flashcard 12: What is the slope at (0,1)(0, 1)(0,1) for dy/dx=1xdy/dx = \frac{1}{x}dy/dx=x1​?

Answer: Slope is undefined. Division by zero creates undefined slope.

Flashcard 13: What does a vertical line segment in a slope field indicate?

Answer: The slope approaches infinity. Infinite slope means vertical tangent line.

Flashcard 14: What effect does a negative slope have on a slope field?

Answer: Lines tilt downward from left to right. Negative slope creates downward-slanting segments.

Flashcard 15: Which direction do lines in a slope field point for dy/dx=−1dy/dx = -1dy/dx=−1?

Answer: Lines point downward at 45 degrees. Constant negative slope creates uniform downward tilt.

Flashcard 16: What is the slope at (2,0)(2, 0)(2,0) for dy/dx=1ydy/dx = \frac{1}{y}dy/dx=y1​?

Answer: Slope is undefined. Division by zero creates undefined slope.

Flashcard 17: What information can you obtain from a slope field?

Answer: The general shape and behavior of solution curves. Reveals overall patterns and equilibrium points.

Flashcard 18: What does each line segment in a slope field represent?

Answer: The slope of the solution curve at a given point. Each segment shows the tangent direction at that point.

Flashcard 19: How do you sketch a slope field for dy/dx=ydy/dx = ydy/dx=y?

Answer: Compute m=ym = ym=y at grid points. Evaluate yyy at each grid point for slope.

Flashcard 20: How do you find the slope at (x,y)(x, y)(x,y) for dy/dx=x2+y2dy/dx = x^2 + y^2dy/dx=x2+y2?

Answer: Compute x2+y2x^2 + y^2x2+y2 at (x,y)(x, y)(x,y). Evaluate the expression at each grid point.

Flashcard 21: How is a slope field constructed for dy/dx=x+ydy/dx = x + ydy/dx=x+y?

Answer: Compute slopes at grid points using m=x+ym = x + ym=x+y. Substitute coordinates into the differential equation.

Flashcard 22: Which direction do lines in a slope field point for dy/dx=−1dy/dx = -1dy/dx=−1?

Answer: Lines point downward at 45 degrees. Constant negative slope creates uniform downward tilt.

Flashcard 23: What effect does a negative slope have on a slope field?

Answer: Lines tilt downward from left to right. Negative slope creates downward-slanting segments.

Flashcard 24: What does a vertical line segment in a slope field indicate?

Answer: The slope approaches infinity. Infinite slope means vertical tangent line.

Flashcard 25: What is a key feature of slope fields for dy/dx=y/xdy/dx = y/xdy/dx=y/x?

Answer: Lines are radial from the origin. Lines point away from origin along rays.

Flashcard 26: What effect does a positive slope have on a slope field?

Answer: Lines tilt upward from left to right. Positive slope creates upward-slanting segments.

Answer: The slope pattern repeats across an axis. Pattern mirrors across coordinate axes.

Flashcard 28: How is dy/dx=0dy/dx = 0dy/dx=0 represented in a slope field?

Answer: Horizontal line segments. Zero slope creates flat line segments.

Flashcard 29: What does a horizontal line segment in a slope field indicate?

Answer: The slope is zero at that point. Zero slope means no vertical change.

Flashcard 30: What is the slope at (0,1)(0, 1)(0,1) for dy/dx=1xdy/dx = \frac{1}{x}dy/dx=x1​?

Answer: Slope is undefined. Division by zero creates undefined slope.
