Note:
Any algebraic or trigonometric equation can be solved in this area of the calculator BUT only one solution is found at
any one time (based on the Newton-Raphson Method), hence multiple solutions to equations should be solved in the
GRAPH icon from the MAIN MENU.
Conics
Conics [7] The use of this mode can see the user investigate the properties of the
conics sections. Varying the expressions for standard conic equations the student can
investigate the conics and their associated equations and properties.
Use the arrow keys to select the conic type required. Note also that the different
selections are for various ways of drawing and nding focal points, directrix, asymptotes
and centres of the parabola, ellipse, circle and hyperbola. You are also able to select
rectangular, polar or parametric formats for each of the conic sections.
