if the vertical plane in which angle of dip is Î´1 subtends Î±ngle Î± with magnetic meridian ,the other vertical plane in which angle of dip is Î´2 subtends Î±ngle (90-Î±) magnetic meridian ;so

tanÎ´1 =B_vB_hcos Î±

tanÎ´2 =B_vB_hcos(90-Î±)

and hence cot2Î´1+cot2Î´2 =(B_hB_v)²[cos²Î±+sin²Î±]

cot2Î´1+cot2Î´2 =cot2Î´
