If a function has several solutions, then the solution that PTC Mathcad finds is based on the initial guess you give PTC Mathcad. For now, we will focus on using the root function. We will also discuss solving multiple equations with multiple unknowns. In later sections, we will discuss finding all the solutions to a polynomial function. Root Function The root function is used to find a single solution to a single function with a single unknown. Provide several engineering examples which illustrate the use of each method of solving equations.Įssential PTCÒ Mathcad PrimeÒ 3.0.

Illustrate how to use units in solving equations. Show how to use a solve block using find, maximize, and minimize to solve multiple equations with multiple unknowns. Show how a plot is useful to determine the initial guess. Discuss the two different forms that it takes: unbracketed and bracketed. Some of the functions discussed require initial guess values, thus a plot is useful to help select the initial guess. This helps to visualize the solution before using PTC Mathcad to solve the equations. As discussed in Chapter 8, when trying to solve for an equation, it is very useful to plot the equations. Because these are some of the most useful functions for engineers, this chapter will use many examples to illustrate their use. The intent of this chapter is to illustrate how engineering problems can be solved using the PTC Mathcad functions root, polyroots, and Find. In this chapter, we will add more solving tools to your PTC Mathcad toolbox. In Chapter 10, we introduced the keyword “solve” with the symbolic evaluation operator. It ranks up there with the use of units as one of PTC Mathcad’s best features. Solving engineering equations is one of PTC Mathcad’s most useful power tools. Once you begin using the solving features of PTC Mathcad, you will wonder how you ever got along without them.
