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!
