(Solved):
Suppose R(t) is a differentiable vector function for t> -1 with R'(t) = (tri +2); 1+t' 1+ t ...
Suppose R(t) is a differentiable vector function for t> -1 with R'(t) = (tri +2?²); 1+t' 1+ t² R(0) = (1, 1, -1). 1. Find R(t). 2. Give the vector equation of the line tangent to the curve defined by R(t) at (1,1,-1) 3. Evaluate (Rof)'(0) if f(t) = 2et. 1+ t and
