Tutorial Exercise Use Part 1 of the Fundamental Theorem of Calculus to find the derivative of the function. G(x) = / cos vet dt Step 1 By the Fundamental Theorem of Calculus Part 1, we know that if g(x) = / f(t) dt, then O g' ( x ) = F (x). O g' ( x ) = 0. O g' ( x ) = F( x). O g' ( x ) = a. O g' ( x ) = f'( x ). Step 2 We know that if ( R( x ) ox = A , then ( F( x ) ox = Submit Skip (you cannot come back)
