In the curve `x= a (cos t+ log tan(t/2))`,` y =a sin t`. Show that the portion of the tangent between the point of contact and the x-axis is of constant length.

The parametric equation of a curve is given by, x=a(cos t+log tan(t/2)) , y=a sin t. Prove that the portion of its tangent between the point of contact and the x-axis is of constant length.

Find dy/dx if: x= a(cos t + log tan (t/2)), y= a sin t

If x=a(cos t + log tan (t/2)) , y =a sin t then (dy)/(dx)=

Find the dy/dx when x = a[cos t + log tan (t//2)], y = a sin t

Find (dy)/(dx) when : x=a(cos t+"log tan"(t)/(2)), y=a sin t

If x = a[cos t + log tan (t/2)], y = a sin t then find (dy)/(dx) .

Find (dy)/(dx)," if "x=a(cos t+log tan""t/2), y=a sin t .
