The +c is to represent the loss in information after differentiation. Remember, integration is just the reverse of differentiation. Say we had this function:

f(x) = 2x^2 + 1 And we differentiate: f...

When we have numbers that are smaller than 1 we use the coma to help us multiplie by 1000. As there are 3 zeros in 1000, we will move the coma on 0.032 3 times to the right to make it bigger. So once woul...

Take 2 equations say equation 1: 2y+4x=26 and equation 2: y+3x= 18. What we need to do is make either the two x values or the 2 y values be equal so that we can subtract one of the equations from the othe...

When simplifying algebraic fractions, first times all the components by the denominator (number on the bottom) of the first component. In this case, that is 3. x/3 times 3 = x and x/4 time 3 = 3x/4. This ...

4x +7 = 13 4x = 6 x=6/4 x=3/2
