Hello i need to solve for x in the this problem to prove the range
y= sqrt((1-x2)/(1+x2))
We are given:
To remove the radical, square both sides:
Now multiply through by:
Arrange with terms involvingon the left, and the rest on the right:
Factor the left side:
Can you proceed from here?
Hmmm, im sorry you'll have to excuse my lack of knowledge. I haven't had math courses of any kind for several years. What is the final step you did factoring the left side. How did you completely get rid of one x^2
Oh nvm i got it. So then would you divide out the (1+y^2) and then take the square root of the whole thing?
Yes, exactly! :)
awesome thanks for the help!
