Math help please...bet not even u can help me with these?

Question

1) in what quadrant does the terminal side of 23pi/20 lie

2) evaluate the following function.... cot 150degree

PLEASE HELP ME.......... im good at math, but i don't get these questions

Answer 1

sarcasm will not get you far in life.... so maybe think about changing the way you get/ask people to do things for you...

23pi/20  = 23*180/20 = 207,  -->  3rd Quad

for number two, just use a calculator

it's the   tan^-1    button on the calc

good luck

Answer 2

Q III  pi < 23pi/20 < 3pi/2

cot 150 = - cot 30 = - tan 60 -sqrt(3)

tan^-1 on the calc is not 1/tan,

it is arctan, the inverse fn of tan.
