## Radical Equation Posted by: Kisung Y on Apr 09, 2018

There are many kinds of equations out there in math. One of them is the radical equation. The radical is this, √, but this is actually a square root, but I will explain. Each of these equations has the same basic concept of trying to isolate the variable to try to make it equal. In…

## Parametric functions differentiation Posted by: Rahulakumar S on Apr 09, 2018

In general, to find the derivative of a function defined parametrically by the equations x=u(t), y=v(t), we use the following rule dy/dx=(dy/dt).(dt/dx)=v(t)/u(t)

## Second Derivative parametric function Posted by: Rahulakumar S on Apr 09, 2018

x=u(t) dx/dt=U'(t) y=v(t) dy/dt=v'(t) dy/dx=dy/dt.dt/dx d2y/dx2=d/dt(dy/dx).dt/dx

## What are the properties of quadrilaterals? Posted by: Kisung Y on Apr 04, 2018

In geometry, the parallelogram and the trapezoid are the fundamental quadrilaterals respectively to classify their own type. The types of parallelograms are the rectangle, rhombus, and square. The types of the trapezoid are the isosceles trapezoid and a right trapezoid.
