Question

How can we smoothen the following graph of sin (t) and cos (t) into a circle?

(a) reduce the gap between linearly spaced elements of the dependent variable t

(b) reduce the gap between elements of the dependent variable t

(c) increase the gap between linearly spaced elements of the dependent variable t

(d) increase the gap between elements of the dependent variable t

I got this question by my school principal while I was bunking the class.

My question is taken from Two-Dimensional Plots in division MATLAB Graphics of MATLAB

Answer 1

Correct answer is (a) reduce the gap between linearly spaced elements of the dependent variable t

To explain: If we reduce the gap between the linearly spaced variables of t, the curvature of sin(t) would be clearly plotted by the plot command. Hence, the resultant curve would be a circle.
