Two reasons: 1. You actually have a negative angle there. 2. It should be the sin function.
Can someone point out where I am going wrong?
The vector in the drawing has a magnitude of 750 units.
(a) Determine the magnitude of the x and y components of the vector , relative to the black axes.
Ax = 650 units
Ay = 375 units
(b) Determine the magnitude and direction of the x and y components of the vector , relative to the colored axes.
Ax' = 575 units
Ay' = 482 units
My question is why is Ay' not just 750cos50?
