We know that slope correction is L(1-cosθ) and this is only correct..If you take sec then where that denominator will go then? Please anyone explain me.

AB not equal L it Lcosθ.

l is slope length and D is the horizontal distance and θ angle of slope.
Now the error is;
L-D.
L-Lcos(θ)
L(1-cos(θ)) this is error always positive.
Correction = - error.
= - [L (1-cos(θ)].
= L[cos(θ) -1].
This is my answer.
Now the error is;

L-Lcos(θ)

Hypotensual correction: L(secθ-1).
Slope correction: L(cosθ-1).
Thank you!
Slope correction: L(cosθ-1).
Thank you!

@All
Correction along with hz line = L(cosθ-1).
Correction along with slope= L(1-cosθ) or L(secθ-1).
Correction along with hz line = L(cosθ-1).
Correction along with slope= L(1-cosθ) or L(secθ-1).
