Q5. Find the derivatives of the functions. (a) fox) = px2 Sin(t?) dt Vx (b) g (x) = sinc cos ( J x2+ 1 )). Fundamental Theorem Calculus Part 2 from Part ! The Fundemental Theorem of Cabins Let I be can amiderivative of f Part " hat fo be a continuous function on Carlo] Then + Part 2. Let It be a continuous function on Buy Part 1, We have G ( = feri Cab] and F'= f Since.
