15. Using Trig, Matrix, and Engineering Functions
Scientists, mathematicians, and engineers, as well as high school mathematics students, will get the broadest use out of the functions in this chapter. Even though many of the trigonometry functions might seem intimidating, this chapter includes practical household examples for many of the functions. Anyone who has to lean a ladder against a house can find a use for the trig functions.
The imaginary number functions might be useful only to electrical engineers, but any business analyst can make use of the techniques for solving linear equations.
Excel 2013 debuts 24 new functions in this chapter:
