Question

Convert 1+2
_
1-2 into polar form

Answer 1

Convert from rectangular coordinates (x,y) to polar coordinates (r,θ) using the conversion formulas. r=√x2+y2. θ=tan−1(yx)

Replace x and y with the actual values. r=√(1)2+(−2)2. θ=tan−1(yx)

Replace x and y with the actual values. r=√5. θ=tan−1(−21)
