Let PM be the perpendicualr from the point P(1, 2, 3) to x-y plane. If bar(OP) makes an angle theta with the positive dirction of z-axis and bar(OM) makes an angle phi with the positive direction of x axis, where O is the origin and theta and phi are acute angles, then

Answer»

`TAN theta=(SQRT(5))/(3)`
`sin theta sin phi=(2)/(sqrt(14))`
`tan phi =2`
`COS theta cos phi=(1)/(sqrt(14))`
