Finding the area of polar coordinates: one petal of r = cos 5 theta.

i know how to compute the area, i just need to check if i've got the correct limits. i got pi/2 and zero.

We need the limits to provide r=0 or cos(5x) =0 so:

5x = pi/2 --> x = pi/10

5x = 3pi/2 --> x = 3pi/10

So the limits should be pi/10 to 3pi/10. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
