A function g(x) is said to be antiderivative of f(x) if . Check instructions to read instructions for using this GeoGebra applet whose aim is to strengthen the concept of antiderivative by giving practice on finding antiderivative. Do not click button Next Problem until antiderivative of displayed function is found out. Feedback will be given once the answer is entered in the antiderivative box. Use asin(x) for arcsin(x) or etc. For more on antiderivative of functions check my online book "Flipped Classroom Calculus of Single Variable"
