Question Number 86198 by Rio Michael last updated on 27/Mar/20

any methods to sketch these curves

r = a (1 - \cos θ)

r = a + b \cos θ a > b

r = a + bcos θ a < b

To sketch any graph you have to keep in your

mind the following things

i) Symmetry : whether the graph is symmetric

respect to X, Y axis or to the line y = x or to the

origin .

ii) Intercept : the intercept of x and y axes

iii) asymptotes : whether the curve has any asymptotes

iv) extension or range of the curve

v) Any special point

Now go and sketch the curve . Good luck
