    Mti mkubwa zaidi duniani kwa kiasi, jina lake General Sherman, unasimama\(274.9\) miguu mirefu na hukaa Kaskazini mwa California. Wanasayansi wanajuaje urefu wake wa kweli? Njia ya kawaida ya kupima urefu inahusisha kuamua angle ya mwinuko, ambayo hutengenezwa na mti na ardhi kwa uhakika umbali fulani mbali na msingi wa mti. Njia hii ni ya vitendo zaidi kuliko kupanda mti na kuacha kipimo cha muda mrefu sana cha mkanda.

    Kielelezo\(\PageIndex{1}\): Mkuu Sherman, mti mkubwa zaidi duniani. (mikopo: Mike Baird, Flickr)

    Katika sura hii, tutazingatia matumizi ya trigonometry ambayo itatuwezesha kutatua matatizo mengi ya aina mbalimbali, ikiwa ni pamoja na kutafuta urefu wa mti. Sisi kupanua mada sisi kuletwa katika Trigonometric Kazi na kuchunguza maombi kwa undani zaidi na maana.
