How To: Solve complex indefinite integrals in calculus

In this video the math teacher explains the meaning of the indefinite integral formula in calculus by stating it in terms of antiderivatives. He then shows in general terms how this indefinite integral formula has a related derivative formula, i.e. if the derivative of F(x) is f(x) then the indefinite integral of f(x) is F(x) plus a constant term (C). With this general relationship the teacher takes us through three related examples where he converts a derivative formula to an integral formul...

How To: Calculate friction in a body without acceleration

This video shows the viewer how to calculate friction in a body that it is not accelerating. The simple answer is that the force of friction will be equal to the force needed to maintain the constant speed. This means that is you pull a wooden block along a carpet at a constant speed and a Newton meter between you and the block measures 5 Newton’s then the force of friction between the carpet and the block is exactly 5 Newton’s. If the object is accelerating then this rule does not apply.For ...

How To: Find a formula describing direct variation

In this video the instructor shows how to find a formula describing direct variation between two variables. Variation between two variables can be either direct variation or indirect variation. If a variable y is in direct variation with a variable x we can write the general equation between them as y = k * x. That is as x varies, y varies directly in relation to x, as a multiple of x. Now if you have the values of y and x, you can substitute them in this general equation which gives you the ...

Under the right condition, it may even cause...

How To: Find the midpoint of a line segment

A good place to start when you want to learn how to find a midpoint of a line is a circle. Take the diameter of a circle, for instance if the coordinates of the starting point are (1,6) and the coordinates for the ending point are (11,6). The midpoint of a line is the exact central point where a line through these two points would meet. Now the value of y is a constant one as the line runs parallel to the x-axis, the value of x changes by 10, the half of which is 5, this is not the midpoint t...
