Find r(t) if r'(t) = 3t2i + 4t3j + t k and r(1) = i + j.

To solve this problem what you should do is follow the following steps:
 Step 1: Integrate both sides of the equation
 Step 2: find the value of the integration constants using the initial condition r (1) = i + j
 Step 3: Write the result with the integration constants.
