siny dx + sqr(2- x^2) dy
This is NOT a differential equation - there is no "equal to" sign.siny dx + sqr(2- x^2) dy
I thought that you like a challenge.This is NOT a differential equation - there is no "equal to" sign.
Since nitpicking is my second name, I'd point out that this is not an equation at all, differential or notThis is NOT a differential equation - there is no "equal to" sign.
I didn't know this identity. This forum is great.Hint:\(\displaystyle \ \csc y + \cot y = \cot(\frac{y}{2})\)
Where did that "= 0" come from?\(\displaystyle \sin y \ dx + \sqrt{2 - x^2} \ dy = 0\)
There are two equations above. Which one is invalid?Where did that "= 0" come from?
\(\displaystyle -\int \frac{1}{\sin y} \ dy= \int \frac{1}{\sqrt{2-x^2}} \ dx\)
Hint:\(\displaystyle \ \csc y + \cot y = \cot(\frac{y}{2})\)
The equation above is incorrect. Please check and modify and repost.
The one relating '(y)' & (y/2) - without calculus.There are two equations above. Which one is invalid?
I suggest that we stay above use of sarcasm. Can be misconstrued.I didn't know this identity. This forum is great.
My MISTAKE ... Still at the corner......Hint:\(\displaystyle \ \csc y + \cot y = \cot(\frac{y}{2})\)
Yeah sorry i forgotThis is NOT a differential equation - there is no "equal to" sign.
Thank you all for reply.. I can't believe that i made two mistake in this equation >_< .. actually it should besiny dx + sqr(2- x^2) dy
Thanks for helping.... actually i made a mistake its arc siny not siny :-(\(\displaystyle \sin y \ dx + \sqrt{2 - x^2} \ dy = 0\)
\(\displaystyle -\int \frac{1}{\sin y} \ dy= \int \frac{1}{\sqrt{2-x^2}} \ dx\)
Hint:\(\displaystyle \ \csc y + \cot y = \cot(\frac{y}{2})\)
[imath]\arcsin(y)\,dx + \sqrt{2- x^2}\,dy = 0[/imath] is a separable equation. Can you separate and integrate?Thank you all for reply.. I can't believe that i made two mistake in this equation >_< .. actually it should be
arc sin (y) dx + sqr(2- x^2) dy = 0
its more difficult know its a homework proplem.... we only study line
Thanks for helping.... actually i made a mistake its arc siny not siny :-(
I thought that was your middle name.....Since nitpicking is my second name, I'd point out that this is not an equation at all, differential or not
Who is nitpicking now ?I thought that was your middle name.....
I am NOT nitpicking - I am quibbling .......Who is nitpicking now ?
