If z=f(x,y), where x=rcosθ and

If z=f(x,y), where x=rcosθ and y=rsinθ, show that (∂^2 z/∂y^2)=(∂^2 z/∂r^2)=(1/r^2)(∂^2 z/∂θ^2)+(1/r)(∂^2

Convert the equation to polar form.8x=8y So far, I got this: 8*rcosθ = 8*rsinθ But it's wrong.

Convert the complex no. In polar form : 1-ircosΘ =1 rsinΘ=-1 r=√a2+b2 r=√(1)2+(-1)2 r=√2 TanΘ=b/a =1/-1 =-1 After all
