The polar form is =5( cos 126.9 º+is in 126.9 º )
Step-by-step explanation: Let z=a+ ib a complex number
The polar form is z=r(cosθ+i sin θ)
r=√a 2+b 2
Here, we have z=−3+4 i
∴r=√9+16=√25=5
z=5(−3/5+4i/5)
∴cosθ=−3 and sinθ=4/5
So, θ is in the second quadrant
θ=126.9 º z=5(cos 126.9 º+i sin 126.9 º)
