How To: Define an antiderivative in calculus

The relationship and the definition of derivatives and anti-derivatives is described in this video. First, consider a function F(x)=x^3-5x+2 and another with small 'f', f(x)=3x-5. f(x) here is the derivative of F(x). However, on the contrary, F(x) is said to be the anti-derivative of f(x). There is a catch though; even though F(x) has only one derivative in the form of f(x), f(x) here has more than one anti-derivative. This is because f(x)'s anti-derivatives are of the form F(x)=x^3-5x+c, whe...

How To: Solve single-step equation by taking the reciprocal

In this video tutorial the instructor shows how to solve a single-step equation by taking the reciprocal. He says that in the equations of fractions containing a variable on the one side, you multiply the reciprocal of its numerical constant to it so that only the variable x stays out. Similarly we need to multiply the reciprocal value that we used on the left hand side on the right hand side too to maintain the equality. Now after simplification as only x is left on the one side we get its v...

How To: Understand Newton's second law

In this tutorial the author explains the concept of Newton's Second Law of motion which states that force is equal to mass times acceleration. So the equation to compute force F is F = m * a, where m is the mass of the body and a is the acceleration produced by the force on that body. He explains that even our weight is our mass times the gravity. So now he explains that mass of a body is constant and only our weight changes depending up on the situation we are in. If you want a clear underst...

How To: Land a Nitro RC plane

First of all you have to loose the altitude by taking a circle or two around in the air. On the final turn make a good straight approach to runaway and don't use too much ‘ailerons’ then. Just use the controls ‘rudder’, ‘elevator’ and ‘throttle’. Also watch for the cars or the traffic where you are going to land. Keep constant low ‘throttle’. You have to maintain good ‘idles speed’. You might want to adjust and remember the trim settings. After touch down, don’t pull on elevator. Just cut the...
