here's an awesome way to approach this.
see that 90 degree angle there? ok. that means that this question is really asking where the point (-√3, 1) would go if the paper were rotated clockwise by 90 degrees.
so...
draw that point on your paper, and then physically rotate the paper by 90 degrees.
originally the x coordinate was negative √3 (to the left). when you rotate the paper, this is now upward, so it's positive √3 in the y direction.
originally the y coordinate was positive 1 (upward). when you rotate the paper, this is now to the right, so it becomes positive 1 in the x direction.
ergo, new coordinates = (1, √3)
