The locus of the point represented by ` x = 3 (cos t + sin t ) , y = 2 ( cos t - sin t ) ` is

x = a (cos t + sin t), y = a (sin t-cos t)

x=a cos t, y=b sin t

The curve represented by x = 3 (cos t + sin t), y = 4 (cos t- sin t) is an ellipse whose eccentricity is e, such that 16e^2 + 7 is equal to:

The curve represented by x=2(cos t+sin t) and y=5(cos t-sin t) is

x=a (t-sin t) , y =a (1-cos t)

x = "sin" t, y = "cos" 2t

Prove that the curve represented by x=3(cos t+sin t),y=4(cos t-sin t),t in R is an ellipse

The graph represented by x=sin^(2)t,y=2cos t is

If x=a(cos t+t sin t) and y=a(sin t-t cos t)

The graph represented by x=sin t,y=cos^(2)t is
