nvm i see where i messed up

#

wait no.

#

i didnt mess up

copper stream
#

the answer is 1

#

-1

neon plaza
#

how so

copper stream
#

whats the value of cos(4pi/3)?

#

alright tell me

#

can you write 4pi/3 as pi + pi/3?

neon plaza
#

-1/2

copper stream
#

yes

neon plaza
#

x2

#

=-1

copper stream
#

yea

#

ye

neon plaza
#

i see where i messed up

copper stream
#

nah its correct

#

you aint messed up

neon plaza
#

i didnt finish my problem

#

which is why i got it wrong on the exam

copper stream
#

oh

#

just write the value of it

neon plaza
#

im going over my exam question at the moment i got wrong

#

professor said to answer the wrong ones correctly

copper stream
#

your exam cant be as bad as mine

neon plaza
#

im sure mine is not remotely close

copper stream
#

the highest in the entire school was 73/100

neon plaza
#

trig is entry level math

copper stream
#

theres like 500 kids

neon plaza
#

im not ready for calc

copper stream
#

trust me calc is not that bad

neon plaza
#

what was the median>

#

i heard calc 2 is kinda wild

copper stream
copper stream
neon plaza
#

is he going to curve it?

copper stream
#

who curves what?

neon plaza
#

usually professors here in US well some

#

if the entire class gets around 30-40%

copper stream
#

in india its completely messed up

neon plaza
#

they usually curve it

copper stream
#

the only thing they care about is problem solving

neon plaza
#

ends up being like 70-80

copper stream
#

we just have ranks

neon plaza
#

i dont really know how it works

copper stream
#

he problem is the population

neon plaza
#

ii know yall in india are built diff

#

super brain soldiers

copper stream
#

they teach us a butt ton of problem solving

#

very les theory

neon plaza
#

i keep seeing it and dont see where its wrong at all

copper stream
#

sure

#

ill see if i can do it

neon plaza
#

its simple argute

#

this is so easy for u

copper stream
#

nahh bro i might get cooked

#

lemme try

#

yeah its almost right

#

i think the answer is -6.3

neon plaza
#

i dont see how i messed up tho

#

tan 9 is .158

copper stream
#

its the value of -cot9

neon plaza
#

i rounded it to 1.6

copper stream
#

see the method i did it is

#

i took cot171 as -cot9

#

because cot171 = cot(180-9)

neon plaza
#

i know

#

and cot is 1/tan

copper stream
#

yes

neon plaza
#

cot9 = 1/tan9

#

i simplified tan 9 first

copper stream
#

yes

neon plaza
#

then divided it to 1

#

because when i just dived

#

divided

#

1/tan9 i get 6.3

copper stream
#

yes

#

thats the answer

neon plaza
#

when i do 1/.16 its different

copper stream
#

yes

#

because thats a rounded off answer

neon plaza
#

u right

#

i in total got 4 answers wrong

#

the next one totally stumped me

#

i dont know how i got this wrong

#

or where i messed up that is

copper stream
#

lemme try

#

am bad at circles

neon plaza
#

all i gotta do is find perimeter and area

copper stream
#

is the answer 34.525?

neon plaza
#

answer is 34.525 for which one

#

area or perimeter

#

we have to find it in radians

copper stream
#

in radian?

#

but they gave 72 degrees

#

you still get area in square units

#

doesnt make a differnece

neon plaza
#

or maybe im wrong i dont know

copper stream
#

that shouldnt make a difference

#

area would be same
