A) \[\text{Parameters: A=B, a=2b;}\delta \text{=}\frac{\pi }{2};Curve:Circle\]
B) \[\text{Parameters: A=B, a=b;}\delta \text{=}\frac{\pi }{2};Curve:line\]
C) \[\text{Parameters: A}\ne \text{B, a=b; }\delta \text{=}\frac{\pi }{2};Curve:\text{Ellipse}\]
D) \[\text{Parameters:}A\ne B,a=b;\delta =0;\text{Curve : Parabola}\]
Correct Answer: C
Solution :
Lissajous curves take common shapes depending on the variables in the expressions. \[x=A\sin (at+\delta )\] \[y=B\sin (bt+r)\] If \[A\ne B\And a=b\] we obtain ellipseYou need to login to perform this action.
