Thread: Changing Polar to Rectangular Short Urgent Help

Transform the equation to the corresponding rectangular coordinate Equation:

y=x.

Let me explain.
y=x (the upper part) makes an angle of pi/4.

But if we consider the negative radius r, in polar coordinates we also get the lower part.
Thus we get a full line.

Hello, ^_^Engineer_Adam^_^!

Transform: .θ = π/4 to rectangular form.

Take the tangent of both sides: .tanθ .= .tan(π/4)

and we have: .tanθ .= .1
. . . . . . . . . . . ↓
. . . . . . . . . . . y
. . . . . .then:. .-- .= .1
. . . . . . . . . . . x

Therefore: .y .= .x
