sketch the curve using the parametric equation to plot the points. use an arrow to indicate the direction the curve is traced as t increases. Find the lenghth of the curve for o<t<1. Find an equation for the line tangent to
Find the equation of the normal to the curve f(x) = 3cos(2x) at the point x = 0. In class, we learnt to find the derivate of the function, which would represent the slope. After I did that, I found the slope to be 0.. but that is
