[Solved] How can you modify the following code to plot two different 3D lines in the same figure?X = 0:0.1:2*pi; plot3(X, sin(X), cos(X), 'b-'); plot3(X, cos(X), sin(X), 'r--'); | MATLAB

MATLAB - 3D Plotting and Visualization

How can you modify the following code to plot two different 3D lines in the same figure?

X = 0:0.1:2*pi; plot3(X, sin(X), cos(X), 'b-'); plot3(X, cos(X), sin(X), 'r--');

AUse <code>figure;</code> before each plot3 call

BAdd <code>grid on;</code> before the first plot3 call

CNo modification needed; code works as is

DAdd <code>hold on;</code> after the first plot3 call

Step-by-Step Solution

Solution:

Step 1: Understand default plot behavior
Without hold on, the second plot3 call overwrites the first plot.
Step 2: Use hold on to combine plots
Adding hold on after first plot3 keeps the first plot visible when second is drawn.
Final Answer:
Add hold on; after the first plot3 call -> Option D
Quick Check:
hold on keeps multiple plots visible [OK]

Quick Trick: Use hold on to plot multiple lines together [OK]
