If `theta_1` and `theta_2` 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

If theta_1 and theta_2 be the apparent angles of dip observed in two vertical planes at right angles to each other, then show that the true angle of dip, theta is given by cot^2theta=cot^2theta+cot^2theta .

If theta_1 and theta_2 be the apparent angles of dip observed in two vertical planes at right angles to each other,then the true angle of dip is give by :

If phi_(1) and phi_(2) be the apparent angles of dip observed in two vertical planes at right angles to each other , then show that the true angle of dip phi is given by cot^(2) phi = cot^(2) phi_(1) + cot^(2) phi_(2) .

If phi_(1) and phi_(2) be the apparent angles of dip observed in two vertical planes at right angles to each other , then show that the true angle of dip phi is given by cot^(2) phi = cot^(2) phi_(1) + cot^(2) phi_(2) .
