Find the dot product of u and v
u= 3i+7j
v= 11i-5j
What is 3*11+7*(-5) ?
To find the dot product of u and v, you need to multiply their corresponding components and then sum up the products.
Given:
u = 3i + 7j
v = 11i - 5j
To calculate the dot product, multiply the corresponding components:
u · v = (3 * 11) + (7 * -5)
= 33 - 35
= -2
Therefore, the dot product of u and v is -2.
