Hello!
Use LaTeX in future for writing equations.
Hint:
My expression is -3=[(-x*pi)/(sqrt(1-x^2))]
An online equation solver gave a solution of x=3/[sqrt(9+pi^2)] or x=.690621 but does not show the working.
I have spent hours on this but am positively stuck!
Can anyone help?
Regards.
Generally speaking, you can only simplify a radical expression that is in factored form.
for example CAN be simplified to
The expression on the other hand cannot be simplfied as-is.
This is especially apparent when you recall that , because the square root would be the same as , which by the same token, is not equal to .
