Question

Pohanginah · Accepted Answer

Given,  z=−5+9i  where,  rcos⁡(θ)=−5 (1)  rsin⁡(θ)=9 (2)  r2(cos2(θ)+sin2(θ))=25+81  r2=106  r=106  From equation (1) and (2)  sin⁡(θ)cos⁡(θ)=−95  tan⁡(θ)=−95  polar form of number  z=r(cos⁡(θ)+isin⁡(θ)  Put values in equation  z=106(cos⁡(tan⁡{−1}(−95))+isin⁡(tan−1(−95)))  Exponential form  z=eriθ  z=106eitan−1(−95)
