r(x)=(e^xsin(x), e^x, e^xcos(x))
find the parametric equations for the tangent line at x=0 and pi/2
can someone help me with this
where t is the parameter. The parametric equations for the curve are:
So I take it that you are trying to find the equation of the tangent line corresponding to the parameters t=0, and then the tangent at correct?
The components of the derivative of a vector function are the derviatives of the components.
Now just plug in the given parameters.
