Question

If a unit vector a makes angle pi/3 with i pi/4 with j

Answer 1

Vector will be  $\frac{1}{2}i+\frac{1}{\sqrt{2}}j$

Step-by-step explanation:

Here i consider that we have to find the vector formed

Magnitude of unit vector is 1

As it makes an angle of $\frac{\pi }{3}$ with i

So x component will be $icos\frac{\pi }{3}=\frac{1}{2}i$

And j makes an angle of $\frac{\pi }{4}$

So y component will be $jsin\frac{\pi }{4}=\frac{1}{\sqrt{2}}j$

So the vector will be $\frac{1}{2}i+\frac{1}{\sqrt{2}}j$
