At `45^@` to the magnetic meridian, the apparent dip is `30^@`. Find the true dip.

At an angle of 30^(@) to the magnetic meridian, the apparent dip is 45^(@) . Find the true dip:

At 45^(@) to the magnetic meridian the apparent dip is 60^(@) . The true dip is

At 45^@ to magnetic meridian, the apparent dip is 30^@ . What is the true value of dip?

The correct value of the dip angle at a place is 45^@ . The dip circle is rotated through 45^@ out of the magnetic meridian. The apparent angle of dip will be :

The dip at a place is delta. For measuring it, the axis of the dip needle is perpendicular to the magnetic meridian. If the axis of the dip needle makes angle theta with the magnetic meridian, the apparent dip will be given tan delta_(1) which is equal to:

The dip at a place is delta. For measuring it, the axis of the dip needle is perpendicular to the magnetic meridian. If the axis of the dip needle makes angle theta with the magnetic meridian, the apparent dip will be given tan delta_(1) which is equal to:

The dip at a place is delta . For measuring it, the axis of the dip needle is perpendicular to the magnetic meridian. If the axis of the dip needle makes angle theta with the magnetic meridian, the apparent dip will be given by tan delta_1 =
