So? Prove it. It's a one-step demonstration.
Can someone assist in how I should solve the following equation?
I know that can be converted to
but I'm stumped as to where to go from there. Any pointers would be appreciated.
*edit*
Hah, I hadn't even looked in the back of the book prior to posting this.. it states there's no solution. Is that because there's basically no way to solve the above equation?
Yours was fine. There are many types of statements.
Prove It brought it algebraically to a pretty obvious place, but yours was there already.
Sibstituting A = sin(x)
Your structure
0) The '2' is of little consequence in this argument. I'll mention only sign, not magnitude.
1) What number's recipriocal can have the opposite sign? Only zero (0) could possibly have this property, since zero (0) DOES have this property if we don't mention the reciprocal. We've narrowed it down to one possible suspect.
2) 'A' cannot be zero on the right hand side. Of course, zero (0) doesn't have a reciprocal. We just eliminated our ONLY suspect.
3) Done.
This IS a little ugly, but any valid argument should be acceptable.
