# How to create cubic bezier curve using control points?

How can I create the cubic bezier curve to (6,2) using control points (2,3.8) and (3.8,2)?

What I have tried:

I considered all the points as the control points P0=(2,3.8) P2=(6,2) P1=(3.8,2)

Consider the below equation: ∑ pi Bi,n (u)

where B is the basis function.

and

Bi,n(u)=nCiui(1-u)n-i

SO I derived the equation:

=P0B0,2(u)+P1B1,2(u)+P2B2,2(u)

But I am not able to get anything using this equation. ANy Help?

Edit:

if I consider only two control points i.e P0=(2,3.8) and P1=(3.8,2) then what is the use of point (6,2) and how we determine how much curly the path is?

A cubic bezier curve starting from point $P_0$, ending at point $P_3$ with two control points $P_1$ and $P_2$ is represented by the following,
$$B(t) = P_0(1-t)^3 + 3(1-t)^2tP_1 + 3(1-t)t^2P_2 + t^3P_3, \ \ t \in [0,1]$$
In your question, $P_1, P_2, P_3$ are given but $P_0$ is not satisfied. May be it is $(0,0)$. Please check the source of the question.
