following this

#

I got 2sinα and (π/2)-α but I'm prob wrong

#

yep both wrong

#

Modulus would be -2sinα and argument would be 3π/2-α ig

#

burnt elm Modulus would be -2sinα and argument would be 3π/2-α ig

both correct

#

i got modulus

#

but confused with argument

#

can u check my approach

crude hinge

-arctan(mod(cot alpha))=arctan(cot alpha) (Since cot is less than zero)=3pi/2-alpha
