Answer: Third option
Step-by-step explanation:
A unit vector is a vector that has magnitude 1.
To find a unit vector in the direction of the vector v we must first calculate the magnitude of v and then divide the vector v by its magnitude
The vector v is:
v = -5i - 2j
The magnitude of the vector is:
Now we divide the vector v by its magnitude
Simplifying we have to
Answer:
Step-by-step explanation:
sin(8x) cos(3x) - cos(8x) sin(3x)
sin(8x - 3x) = sin(5x)
