ok let me see

therealmeeeee · Answer

a) integrate 3+cos(t^2) dt ... use initial value of x(2) = 1

Strange...this is supposed to be related rates

anonymous · Answer

Time rates differentiate

anonymous · Answer

this is an equation of circle 
centred at (0,0) and radius 2sqrt(2)
so  from this we can determine x and y coordinates in terms of t  
can we write 
x = 2 *sqrt(2)*cos(wt)
and y = 2*sqrt*sin(wt)   ????????????????

anonymous · Answer

so it's not possible to get exact coordinates ?

anonymous · Answer

Thank you all whoever tried to help me. Closed.

anonymous · Answer

as far as my knowledge is concerned
we need to derivate x and y coordinates w.r.t  separately because we used the circle equation to determine the x and y coordinates
then we are going to equate them both

if u r not satisfied with explanation , can u pls upload  the snapshot of this ques?

anonymous · Answer

I am satisfied, thank you and sorry for taking too long to answer
