Students will review:
In this chapter, you'll find the answers to questions including:
- What are some of the key features of a scientific calculator?
- How do I compute radians and degrees on a scientific calculator?
- How do I solve equations on a scientific calculator?
- What steps do I follow to solve equations by graphing on a scientific calculator?
1. Radians & Degrees on the CLEP Scientific Calculator
In this lesson, we'll review online calculators, in particular the CLEP online calculator. Review the difference between radians and degrees, the order of operations and scientific notation on the CLEP calculator.
2. Trigonometry Functions & Exponentials on the CLEP Calculator
In this lesson, review how to use the history on the CLEP calculator as we calculate sines, cosines and the inverse trigonometric functions. Finish by exploring exponentials and logarithms.
3. Solving Equations on the CLEP Scientific Calculator
In this lesson, learn how to use the Solver function of the CLEP calculator. With calculators, you can solve equations numerically (find a number answer) even when you cannot solve the problem explicitly.
4. How to Solve Equations by Graphing on the CLEP Scientific Calculator
In this lesson, review how to graph equations with the CLEP calculator. Given a function, find the maximum and minimum values over a range and the roots of the equation. Learn how you can use this to solve a system of equations by graphically finding intersects.
