Hello! Vector operations usually involve addition, subtraction, quantity multiplication and dot product. Vector addition is to add the corresponding components of two vectors to get a new vector. Vector subtraction is to subtract the corresponding component of one vector from the corresponding component of another vector to get a new vector. Quantity multiplication is to multiply a scalar with each component of a vector to get a new vector. Dot product is to multiply and add the corresponding components of two vectors to get a scalar value. These basic vector operations are widely used in mathematics and physics such as mechanics, electromagnetism and computer graphics. Mastering vector operation skillfully can better understand and solve various practical problems. Hope to adopt! ! !
