What can you do in this mode ?1:04
Use the Casio Classwiz polynomial mode to solve quadratic and cubic equations, find roots, and analyze turning points. Visualize the graph by scanning the QR code.
Example 1 (Quadratic equation)2:30
Example 2 (Quadratic equation)1:35
Example 3 (Cubic equation)1:22
Example 4 (Cubic equation)0:55
Solve the cubic 6x^3 - 5x^2 - 3x + 2 = 0 on Casio ClassWiz to obtain roots -2/3, 1, and 1/2; scan the QR code to view the curve.

What can you do in this mode ?1:09
Enter the vector mode to define up to four vectors in two or three dimensions, using coordinate form, column vector form, or cartesian form. Perform magnitude, dot product, cross product, angle, and unit vector calculations.
Example 1 (Basic operations: Two dimensional vector)3:26
Example 2 (Basic operations: Three dimensional vector)3:13
Example 3 (Magnitude and unit vector)3:48
Define three-dimensional vectors A, B, and C as A=(1,2,1), B=(3,-5,0), and C=(-8,7,-2) to compute their magnitudes and unit vectors with a Casio Classwiz.
Example 4 (Dot product, cross product and angle between two vectors)2:38

What can you do in this mode ?0:42
Example 1 (Quadratic inequality)1:24
Enter the quadratic inequality into a Casio ClassWiz calculator, obtain x<2 or x>6, and visualize the solution region by scanning a QR code.
Example 2 (Quadratic inequality)0:54
Example 3 (Cubic inequality)1:10
Learn to verify a cubic inequality on the Casio Classwiz by entering coefficients and choosing greater than zero. The result shows x in (-4, -1) and x > 1.
Example 4 (Cubic inequality)1:07
Solve the cubic inequality 3x^3 - 14x^2 - 5x ≤ 0 by calculator input, confirming the solution range lies between 0 and 5, inclusive.
Try it yourself0:50
Find the solution set for 6x^2 - 17x + 12 < 0, with roots at 4/3 and 3/2, giving x in (4/3, 3/2); verify using a calculator and visualize with QR code.

What can you do in this mode ?0:27
Example 10:30
Example 20:32
Example 3 (Similar triangles)1:16
Use similar triangles to verify answers by comparing corresponding sides and their ratios. In the example, x equals 12.
Example 4 (Similar triangles)1:35
Try it yourself0:50
Explore using similar triangles to solve for an unknown side by matching corresponding sides and setting up proportional values, and practice solving for B using X as the corresponding side.
