The root function takes the form root(f(var), var, ). Plot the function prior to giving PTC Mathcad the initial guess. If a function has several solutions, then the solution that PTC Mathcad finds isīased on the initial guess you give PTC Mathcad. We will also discuss solving multiple equations with multiple unknowns.įor now, we will focus on using the root function. In later sections, we will discuss finding all the so lutions to a polynomialįunction. The root function is used to find a single solution to a single function with a single Provide several engineering examples which illustrate the use of each method of #Polyroots mathcad 14 how to#Illustrate how to use units in solving equations. Multiple equations with multiple unknowns. Show how to use a solve block using find, maximize, and minimize to solve Show how a plot is useful to determine the initial guess. Require initial guess values, thus a plot is useful to help select the initial guess.ĭiscuss the two different forms that it takes: unbracketed and bracketed. This helps to visualize the solutionīefore using PTC Mathcad to solve the equations. As discussed in Chapter 8, when trying to solve for anĮquation, it is very useful to plot the equations. These are some of the most useful functions for engineers, this chapter will use manyĮxamples to illustrate their use. The intent of this chapter is to illustrate how engineering problemsĬan be solved using the PTC Mathcad functions root, polyroots, and Find. In this chapter, we will add more solving tools to your PTC 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 Click here for the latest version of SMath Studio.Once you begin using the solving features of PTC Mathcad, you will wonder how youĮver got along without them. #Polyroots mathcad 14 update#Update 3rd April 2010: version 0.85 is now out of date.
