You need to explain how you get things...

man you just taught me better than my math teacher could just by doing this out, thanks a ton

EmilyLimeHadley

I don’t understand how you broke down 5pi/12? Like why those specific fractions???

zechvassar

Very Clear Explanation, thanks so much

mattacosta

Thank you for your explanation. I'm a little confused as to where you got your answer for sinπ/4 and cosπ/4 because I'm getting 1/√2 with a final answer of (√3 +1)/2√2.

Please do another example with a numerator of much greater value such as 41pi over 12.

not the hero we deserve, but the one we need. msolved tutoring saves the day once more. parenthetically, fuck pearson's my math lab.

hanmetalworks

it would be helpful if you could further break this process down.

where do you get the "sin(pi/4+pi/6 ???

kurtbendo

i understand everything but the first step. how/ why did he choose 3pi/12 and 4pi/12??

Thank you so much hahaha I've been having a hard time how to answer higher than 10 and this really helped me

Hi, how can you get to the exact result of: 1+(3^0.5)/2(2)^0.5

thanks

Can't we just put the value of pi and get the answer?

eileenkerketta

Can't we convert sin(5pi/12) to sin75 and the further write it as sin(45+30) and then use the formula? I got the answer as [root(3)+1/2.root(2)]

u need to explain how did u get 3pi/12 and 2pi/6

arunkumarpanda

what would be the exact value of csc 5pi/12?

Do you know AP Physics 1? I'm a freshman taking this class and I'm struggling really badly.

PamKitsuwan

"multiply pie over" like where are u getting cos
I'm doing sat practice so I'm totally new to this

If you taught concepts you would get more views and likes and you would help more people :) but still thanks for the help you are good at teaching.
