How would you simplify this polar equation to r=?

2=rcos(theta-20)

Would i divide the 2 by both sides?

  • Precalc -

    yes.

  • Precalc -

    Then how would i bring the r out?

  • Precalc -

    Multiply R by both sides so that u have r equals the rest of the equation

  • Precalc -

    r=2/cos(theta-20) -the equation of a line

  • Precalc -

    why wouldnt it be cos(theta-20)/2?

  • Precalc -

    We divide both sides by cos(theta-20)

    ohhhh wooow why didn't i think of it that way haha thanks!
