यदि `x=2 log cot t ` व `y= tan t+ cot t ,` तब `(dy)/(dx) sin 2t +1=`

If x = log t^2 , y = log t^3 , then (dy)/(dx) is

If x=t^(2) and y=log t , find (dy)/(dx) .

If x= sin (log t ),y =log (sin t ) ,then (dy)/(dx)=

If x= t log t,y = (log t)/t , find (dy)/(dx) when t=1

If x=t log t ,y =t^(t) ,then (dy)/(dx)=

If x=t log t ,y =t^(t) ,then (dy)/(dx)=

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

If x=a(cos t + log tan (t/2)),y=a sin t , then what is (d^2y)/(dx^2) at t=(pi)/3 .

If x = sin t and y = tan t , then (dy)/(dx) is equal to a) cos ^(2) t b) (1)/( cos ^(3) t ) c) (1)/( cos ^(2) t ) d) sin ^(2) t
