I want to create this object in grasshopper, but I cannot.

I want to draw a vector-normal of sin curve that maximizes the length in the +Y direction with π I/2 and in the -Y direction with π 3/4.
I want to learn how to draw this vector line.
So I want to ask anyone who can tell me.
I am sorry to trouble you, but I appreciate your cooperation.
