Verifying Tangents Tell whether AB is tangent to OC. Explain
your reasoning.
To tell if AB is tangent, we must use
Once we use the theorem, we get
- (^ means exponent)
Once solved, we get

\3. yes the presentation (i.e. odd numbers being written as differences of two squares) is possible for all odd natural number however the presentation may not be unique. for example,  57=112−82=292−28257=112−82=292−282.

\4. 2 can't be written as a difference of two squares because 4-1=3 and 1-1=0 and the difference of squares grows to integers larger that 3.

can i get some in proving questions 1 and 2?
