Find the derivative of the function
  f(t)=arccscâ¡ã€–(-t^2)〗
  f(x)=arccotâ¡âˆšx
  y=lnâ¡ã€–t^2 〗-arctanâ¡ã€–t/2〗
  f(x)=arcsecâ¡x+arccscâ¡x
  y=arctanâ¡ã€–x/2〗+1/(2(x^2+4))
  Use implicit differentiation to find an equation ofthe tangent line the graph of the equation at the givenpoint.
arctanâ¡(x+y)=y^2+Ï€/4, (1,0)
