If  be the apparent angles of dip observed in two vertical planes at right angles to each other, then the true angle of dip $\theta$ is given by

(1) $co{t}^{2}\theta =co{t}^{2}{\theta }_{1}+co{t}^{2}{\theta }_{2}$

(2)

(3) $co{t}^{2}\theta =co{t}^{2}{\theta }_{1}-{\mathrm{tan}}^{2}{\theta }_{2}$

(4) ${\mathrm{tan}}^{2}\theta ={\mathrm{tan}}^{2}{\theta }_{1}-{\mathrm{tan}}^{2}{\theta }_{2}$

If  and ${\theta }_{2}$ are the apparent angles of dip observed in two vertical planes at right angles to each other, then the true angle of dip $\theta$ is given by:
1. ${\mathrm{tan}}^{2}\theta ={\mathrm{tan}}^{2}{\theta }_{1}+ta{n}^{2}{\theta }_{2}$
2. $co{t}^{2}\theta =co{t}^{2}{\theta }_{1}-co{t}^{2}{\theta }_{2}$
3. ${\mathrm{tan}}^{2}\theta ={\mathrm{tan}}^{2}{\theta }_{1}+ta{n}^{2}{\theta }_{2}$
4. $co{t}^{2}\theta =co{t}^{2}{\theta }_{1}+co{t}^{2}{\theta }_{2}$
