Problem

2*π−π/2

Solution

1. Identify the terms in the expression as multiples of π

2. Find a common denominator for the two terms by rewriting 2*π as a fraction with a denominator of 2

2*π=(4*π)/2

3. Subtract the numerators while keeping the common denominator.

(4*π)/2−π/2=(4*π−π)/2

4. Simplify the resulting expression.

(3*π)/2

Final Answer

2*π−π/2=(3*π)/2
