Question

please make graph of r=4 cos 3 theta with full explanation of how to make it​

Answer 1

Answer:

See graph and explanation.

Explanation:

Using

(

x

,

y

)

=

r

(

cos

θ

,

sin

θ

)

,

r

=

√

x

+

y

and

cos

n

θ

=

∑

(

r

θ

sin

r

θ

,

r from 0 to

[

n

2

]

(integer part of n/2).

the equation in Cartesian form for

r

=

a

cos

n

θ

can be obtained.

Here, n = 3 and the Cartesian equation is

#( x^2 +y^2 )^2 = 4 (x^3 - 3 x y^2),

The Socratic graph is immediate.

graph{( x^2 +y^2 )^2 - 4 (x^3 - 3 xy^2)=0[-8 8 -4 4]}
