Enter a value for all fields

The 4^th Degree Polynomial equation computes a fourth degree polynomial where a, b, c, d, and e are each multiplicative constants and x is the independent variable.  

INSTRUCTIONS: Enter the following:

• (a) Coefficient of x⁴ 
• (b) Coefficient of x³ 
• (c) Coefficient of x² 
• (d) Coefficient of x 
• (e) Constant
• (x) Value of x

4^th Degree Polynomial (y): The calculator returns the value of y.  

Plotting: This calculator has plotting enabled.  You can enter the coefficients (a-e) above, and then provide a range for x in the plot menu.  The plot will show the y = f(x) graph based on the 4^th degree polynomial constants entered.

The Math / Science

A fourth degree polynomial is an equation of the form:

       `y = ax^4 + bx^3 + cx^2 +dx+ e`   

where:

• y = dependent value
• a, b, c, and d = coefficients of the polynomial
• e = constant adder
• x = independent value
