Answer:
 
Step-by-step explanation:
If a complex number is z=a+ib, then the trigonometric form of complex number is
 
where,  and
 and  ,
,  is called the argument of z,
 is called the argument of z,  .
.
The given complex number is -5i.
It can be rewritten as
 
Here, a=0 and b=-5.  lies in 4th quadrant.
 lies in 4th quadrant.
 
 
 
 
    ![[\because \text{In 4th quadrant }\theta=2\pi-\theta]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Ctext%7BIn%204th%20quadrant%20%7D%5Ctheta%3D2%5Cpi-%5Ctheta%5D) 
 
So, the trigonometric form is
 
 
        
                    
             
        
        
        
Answer:
m=a/x+Q
Step-by-step explanation:
Q=m-a/x
To solve this we need to isolate m so we will bring -a/x to the other side of the equal sign so it will become positive i.e. ax now will be  written as a/x+Q=m
in other wards m=a/x+Q
