ohhh you are correct too(No, the photo is vague about that. But anyway:)

If you want the x component to be cosθ, you must integrate from -π/2 to π/2

thanks

If it's like that, then you integrate from 0 to pi, and it will be sin.

If you measure it from the negative x-axis, it will be cos, and the limits will be -pi/2 to pi/2.

You can use both at the same time for different parts of the problem, nothing wrong with that.
