Best ResponseYou've already chosen the best response.0anyways there are many ways to solve this problem, one of them would be Taylor series the other one would be substitution method

Best ResponseYou've already chosen the best response.0i felt like crying lol, with out this website i don't know what id do

Best ResponseYou've already chosen the best response.0ok let me reply to the last integral

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0the answer for the last integral would be pi/6

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0now by looking at the last integral you can find out from the table that it is equal to arcsin(x/2)

mathsmind

Best ResponseYou've already chosen the best response.0\[\int\limits_{0}^{1}\frac{ dx }{ \sqrt{4x^2} }\]

mathsmind

Best ResponseYou've already chosen the best response.0is that the integral or not?

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0ok there are two ways to do that

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0one way is to look at the arctrigs integrals

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0you know the table of integrals right!

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0the other way is to go through full substitution method

Ephilo
 2 years ago
Best ResponseYou've already chosen the best response.0lol no but ill look them up

mathsmind

Best ResponseYou've already chosen the best response.0ok do you want detailed solution then

mathsmind

Best ResponseYou've already chosen the best response.0can you differentiate the last bit?

mathsmind

Best ResponseYou've already chosen the best response.0thanks that was kind of you, and you are a bright student

mathsmind

Best ResponseYou've already chosen the best response.0let me give you a third way how to do that

Ephilo
 2 years ago
Best ResponseYou've already chosen the best response.0i understand the usub the most

Ephilo
 2 years ago
Best ResponseYou've already chosen the best response.0i have three more integral questions

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0you need to know different methods to solve one problem , that for future note...

Ephilo
 2 years ago
Best ResponseYou've already chosen the best response.0altho the differentiate part is a bit hard

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0i have a phone call but still submit your work

Ephilo
 2 years ago
Best ResponseYou've already chosen the best response.0but ill look back it later because i have to get this course done to graduate

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0no i meant you make y =2sinx sub

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0different substitution

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0if you look at the unit triangle you can figure out that you need a sin sub

Ephilo

Best ResponseYou've already chosen the best response.0find the intergal dw:1361286908472:dw

mathsmind

Best ResponseYou've already chosen the best response.0again you are going to get an arctan but now we need to look at the factors

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0just by looking at this integral we will get 4/3arctan(3x) +c

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0the question is what was x=? in this u sub

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0you need to assume that 3x=u, 9x^2=u^2, 3dx=du

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0\[\int\limits \frac{ 4du }{ 3(1+u^2) }=\frac{ 4 }{ 3}\arctan(u)+c\]

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0\[u=3x, \therefore \frac{ 4 }{ 3 }\arctan(3x)+c\]

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0that's your final answer

Ephilo
 2 years ago
Best ResponseYou've already chosen the best response.0okay i just did the other one so i have one more integral question

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0again you can see we will get the arctan + something

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0your answer should be\[\frac{ 1 }{ 2 }\arctan(\frac{ 1 }{ 2}(x1))+c\]

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0\[\int\limits\limits\limits \frac{ dx }{4+(1x)^2}\]

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0now 2u=1x, 4u^2=(1x)^2,

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0now one thing you need to know is how to let the 4 be a one in the denominator

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0ok let me show, it is clear from the usub

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0remember that 2u =1x, 2du=dx

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0\[\int\limits\frac{ 2du }{4(1+(u)^2)}\]

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0can you see it better this way?

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0\[\frac{ 1 }{ 2 }\arctan(u)+c\]

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0\[2u=1x, \space u=\frac{ 1 }{ 2 }(1x)\]

mathsmind

Best ResponseYou've already chosen the best response.0\[\frac{ 1 }{ 2 }\arctan(\frac{ 1 }{ 2 }(1x))+c\]

mathsmind

Best ResponseYou've already chosen the best response.0you don't sound like you got the last one?

Ephilo

Best ResponseYou've already chosen the best response.0lol i havent fully looked at it yet im finishing a problem

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0so i read your mind well hehehe

Ephilo

Best ResponseYou've already chosen the best response.0lol yeahh i was wondering how you knew that,but im looking at it now

Best ResponseYou've already chosen the best response.0i still don't understand how the engagement scheme works on open study

Ephilo

Best ResponseYou've already chosen the best response.0i think its by the questions you answer, and medals you receive

mathsmind
 2 years ago
Best ResponseYou've already chosen the best response.0no i am not asking about those two, i am asking about the engagement part

mathsmind

Best ResponseYou've already chosen the best response.0the one that has learner next to it

Ephilo

Best ResponseYou've already chosen the best response.0lol i thinks its from asking questions cause thats how you learn right

Ephilo

Best ResponseYou've already chosen the best response.0okay i found two i need help on

Ephilo

Best ResponseYou've already chosen the best response.0determine which of the integrals can be found using the basic integration formulas you have studied so far in the text.

mathsmind

Best ResponseYou've already chosen the best response.0i think you need to open a new thread because this one is getting heavy with BW
