sin(π/2 - L) - cos(π - L) - tan(π - L) = cos(L) - [-cos(L)] - [tan(L)] (using trigonometric identities) = cos(L) + cos(L) - tan(L) = 2cos(L) - tan(L) (simplified)
sin(π/2 - L) - cos(π - L) - tan(π - L)
= cos(L) - [-cos(L)] - [tan(L)] (using trigonometric identities)
= cos(L) + cos(L) - tan(L)
= 2cos(L) - tan(L) (simplified)
