(a) coordinates of **P**.

(b) equation of the straight line that passes through **N**(3, -5) and **P**.

**2**. (a) Find the sum of the series 32 + 8 + 2 + …,

(b) Simplify: 1−25−3−1+25+3

**3**. Without using mathematical tables or calculator, find, in surd form (radicals), the value of tan22.5∘.
