An implicit function is a function that is defined implicitly by an implicit equation, by associating one of the variables (the value) with the others (the arguments). Thus, an implicit function for y in the context of the unit circle is defined implicitly by x2 + f(x)2 − 1 = 0.

Ash Varshney 3 years, 10 months ago

The derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′(x) > 0, then f is increasing on the interval, and if f′(x) < 0, then f is decreasing on the interval. ...

Log(dy/dx)=ax+by => dy/dx=e^{ax+by} => dy/dx=e^(ax).e^(by) => dy/e^(by)=e^(ax)dx =>e^(-by)dy=e^(ax)dx Integrating both sides, -e^(-by)/b=e^(ax)/a + c

Sia ? 3 years, 5 months ago

We have given
y = x-7/(x-2)(x-3)......(i)
Let (i) cuts the x-axis at (x, 0)
then x-7/(x-2)(x-3) =0 =>x=7
the required point is (7, 0).
Differentiating equation (i) w.r.t. x, we get
