__Radicals and Quadratic Formula Program__

**I. ****In the definition window, write a Scheme
Expression Test for each of the problems to check your radical worksheet.**

:
**Example: (= (sqrt 8) (* 2 (sqrt 2)))**

:
**You
should get a true in the interaction window if you worked the problem
correctly.**

**II. ****Show ALL steps in the design recipe
to: **

:
**Remember
Process (examples) and feedback (test) are essential
parts.**

**1)
****Write a
program that consumes the coefficients for x^2 - a ,
x - b and the constant c to find the discriminate in the quadratic
formula. **

**2)
****Write a
program that consumes the coefficients for x^2 - a ,
x - b and the constant c to check your answers using the quadratic
formula. **

:
**Hint: Use the auxiliary function for the
discriminate.**

**3)
****Write a
program to find the length of one side of a right triangle given the length of
the hypotenuse and one side. Check using
the new test case method where if your examples were correct, you only get true
in the interaction window. **
