2012 TRIG STAR COMPETITION
Zach Groth, a junior at Rockford East High School is the 2012 local high school TRIG-STAR. A TRIG-STAR is a mathematics student who has demonstrated in competition that they are the most skilled among classmates in the practical application of trigonometry. The competition for the honor is a timed exercise which is the solving of a trigonometry problem that incorporates the use of right triangle formulas, circle formulas, the law of sines, and the law of cosines. The contest helps to promote careers in surveying and mapping to students at the High Schools across the country. The award is sponsored by the National Society of Professional Surveyors and Hampton, Lenzini and Renwick, Inc. State winners also have the opportunity to participate in the National TRIG-STAR competition for awards.
Hampton, Lenzini and Renwick has sponsored this competition annually since 2010. Jeni Lyon, HLR’s survey department manager, demonstrates to the students the practical application of their math skills as it relates to the surveying profession. Then she administers the one-hour exam consisting of several trigonometry problems. This year 36 East High School students participated in the exam.
