Graphing Parametric Equations - Sharp EL-9900C User Manual

GRAPHING PARAMETRIC EQUATIONS

Steps for graphing a parametric function:
1. Turn the calculator on and press 2ndF SET UP
2 (Param) to change to parametric mode. Press 2ndF QUIT
to exit the SET UP menu.
2. Make sure calculator is set to display rectangular coordinates when tracing
by pressing 2ndF FORMAT F (CURSOR) 1 (RectCoord)
QUIT to exit the FORMAT menu.
3. To enter the parametric function X1T = 2(cos T)
Y= CL
X/θ/T/n
X/θ/T/n key provides a T for equation entry.
4. Now, graph the parametric function in the Decimal viewing window by
pressing ZOOM
5. Press TRACE and notice the expression and T values now appear on the
range screen.
