If delta_(1)and delta_(2)be theapparent valuesof the dip observed in two planes at right angles to each other and delta is thetrue valueof the dip then

Answer»

`sin^(2)DELTA=sin^(2)delta_(1)+sin^(2)delta_(2)`
`cot^(2)delta=cot^(2)delta_(1)+cot^(2)delta_(2)`
`tan^(2)delta=tan^(2)delta_(1)+tan^(2)delta_(2)`
`cos^(2)delta=cos^(2)delta_(1)+cos^(2)delta_(2)`
