Question

Vă rog frumos, am nevoie cât mai repede!​

Answer 1

1.

π=180°

$a)\ \frac{\pi}{4}=45$

$b)\ \frac{7\pi}{6} =210$

$c)\ \frac{5\pi}{2} =450$

$d)\ -\frac{3\pi}{2} =-270$

$e)\ \frac{7\pi}{12} =105$

$f)\ -\frac{9\pi}{5} =-324$

$g)\ \frac{100\pi}{3} =6000$

$h)\ -\frac{20\pi}{3} =-1200$

$i)\ \frac{245\pi}{9} =4900$

2.

cadran 1 (0,90°)

cadran 2 (90°, 180°)

cadran 3 (180°, 270°)

cadran 4 (270°,360°)

Pentru valori >360° se ia in considerare {masura unghi:360°}, adica partea fractionara

$a)\ \frac{\pi}{15} =12\ cadran\ 1$

$b)\ \frac{3\pi}{4}= 135\ cadran\ 2$

$c)\ \frac{24\pi}{5} =864=144\ \ cadran\ 2$

$d)\ \frac{8\pi}{3} =480=120\ cadran\ 2$

$e)\ \frac{111\pi}{2} =270\ axa\ dintre\ cadran\ 3\ si \ 4$

$f)\ \frac{707\pi}{3}= 42420=300\ cadran\ 4$

$g)\ -\frac{11\pi}{3} =-300=60\ cadran\ 1$

$h)\ -\frac{23\pi}{6} =-330=30\ cadran\ 1$
