Calculul valorilor unor functii trigonometrice: Calculati valoarea expresiei E1 = sin(150) + cos(200) + tg(500) + ctg(700) sin(150) cos(200) tg(500) ctg(700)

0,25882 0,93969 1,19175 0,36397

E1 =

2,75424

=SIN(15*PI()/180) =COS(20*PI()/180) =TAN(50*PI()/180) =1/TAN(70*PI()/180)

Folositea functiei SIN 1) Se selecteaza celula in care va apare rezultatul. 2) Se apasa butonul fx de pe bara Standard pentru deschiderea ferestrei Paste Function. 3) In fereastra Paste Function se selecteaza functia SIN si se apasa butonul OK. 4) La rubrieca Number se scrie numarul de grade inmultite cu PI()/180. 5) Se apasa butonul OK si rezultatul este inscris in celula selectata.
