Question

if R vector =Avector-B vector R^2=A^2+B^2-2ABcosthita ,where thita is the angle between Avector and B vector?plz ans me +

Answer 1

Hi friend,

In vector studies ,theta is usually common.

It has many branches and it goes on as scalar double product ,triple product ,four product and so on....

It Is mainly classified into scalar and vector product.

Scalar product means dot product.

A(vector).b(vector)=an cos(theta)

For scalar product we add cos theta and for vector product we add sin theta.

I hope this will helps you!!

If you have further any doubts you can ask me!!
