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

A unit vector hata makes an angle pi/4 with z-axis, if hata+hati+hatj is a unit vector then hata is equal to

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 .

Choose the correct answer from the backet. If a unit vector hata makes angles pi/4 with i and pi/3 with j and acute angle theta with k. then theta is

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 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

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
