Question

If Ā.B = ĀxB then the angle between, Ā, B​

Answer 1

Explanation:

is 45°. Well just apply the definition.

A×B= A B Sin(x) C^

While A.B=A B Cos(x)

Substitute in the given equation we get AB Sin(x) = AB Cos(x)

Here direction is not taken as we are dealing with magnitude only as per the condition.

Now Sin(x)= Cos(x)

Finally we get Tan(x)= 1

That is x= 45°

Answer 2

Answer:

45 degrees

Explanation:

a.b= ab costheta

axb= ab sintheta

sin 45=cos45=1/root2
