convert to rectangular form r = 4 / (7sin theta + 29 cos theta)

Question

terenzreignz · Answer

Divide both sides by r. What do you get?

anonymous · Answer

honestly thats what I have been having an issue with... I can't figure out how to switch the r because of the fraction

terenzreignz · Answer

Yeah, well, if you divide both sides by r, you should get 
$$\Large 1 = \frac{4}{r[7\sin(\theta)+29\cos(\theta)]}$$
right?

terenzreignz · Answer

Might have been an inefficient approach.... multiply both sides here by $$\large 7\sin(\theta) + 29 \cos(\theta) $$  instead.

Giving you...
$$\Large r[7\sin(\theta) + 29 \cos (\theta)]=4$$

ah okay I got it now I didnt even think to multiply both sides by the denominator

now its just 7y + 29x = 4

anonymous · Answer

and solve for y for the answer correct?

terenzreignz · Answer

Honestly, I think 7y+29x = 4 is enough
But solving for y is good too :)
