Question

Can someone check if I did this integral right?
I knew the answer to the integral so I do not know if every step along the way is right or if I did because I knew what had to come out in the end.

Answer 1

Here is the integral and what I did to it.

Answer 2

looks right!!

Answer 3

for these stuf ... just plugin into W|A .. probably it also gives step for you.

Answer 4

I was not sure about the last step, where I drew the triangle. Substituting the cos(arcsinx) with the squareroot of 1-x^2.
First time I did such a substitution and since I knew the answer.
Thx for checking it. I really appreciate it.

Answer 5

W|A they are also becoming money lechers
now you can view just three step by step solutions and even for that you have to have registered account ..
that's the reason integral stuff is getting increase on OS !

Answer 6

really?

Answer 7

yes give it a try .

Answer 8

haha lol !!!! yeah thats why i love it too ;)

Answer 9

If you make an (free) account I think you can get a step by step solution for three euqations per day.

Answer 10

yes but people used to get 50 + solution per day ..

Answer 11

haha ... i don't need step by step solution ... if i have final answer ... I'll just differentiate it and reverse engineer and connect to solution. If i go back ... I've the step by step solution.

for final answer I've got bunch of pirate stuff. :P

Answer 12

that's i use sometime
Engineers always think same way :P

Answer 13

lol ... I'm physicist @sami-21 ... but i knew you were engineer :D

Answer 14

lol physicist are engineers brothers :)

Answer 15

hahah ... agreed!!
