A vector field is represented by F = 2 a + za + cos

Question:

A vector field is represented by F = ρ²a_ρ+za_Φ + cos Φa_zNewtons. Evaluate the work done or ∫_L F ∙ dl, where L is from P(2, 0°, 0) to Q(2, π/4, 3). Assume that L consists of the arc ρ = 2, 0 < Φ < π/4, z = 0, followed by the line ρ = 2, Φ = π/4, 0 < z < 3.
