A unit vector a makes an angle `pi/ 4` with z-axis. If `a + i + j` is a unit vector, then a can be equal to

If unit vector a makes angles pi/3 with i, pi//4 with j and theta in (0,pi) with k, then a value of theta is

IF a unit vector veca makes angles pi/4 and pi/3 with x-axis and y-axis respectively and an acute angle theta with z-axis, then find theta and the (scalar and vector) coponents of veca along the axes.

The vector (hat i +hat j) is a unit vector.

If a unit vector "a" makes an angle "pi"/3 with hat"i"," ""pi"/4 with hat"j" and an acute angle "theta" with hat"k", then find the value of "theta"dot

If a unit vector vec a makes an angle (pi)/(3) with hat i,(pi)/(4) with hat j and an acute angle theta with hat k then find theta and hence,the components of vec a

A unit vector in the xy-plane that makes an angle of (pi)/(4) with the vector hat i+hat j and an angle of with the vector 3hat i-4hat j is

If vec b is a unit vector in xy- plane making an angle of (pi)/(4) with the x -axis,then vec b is equal to

If a unit vector vec a makes angle pi/4 with hat i,pi/3 with hat j and an acute angle theta with hat k then find the components of vec a and the angle theta .
