Prove : The perpendicular distance from a point P(x1,y1) to the straight line whose equation is Ax + By + c = 0 is

d = absolute value (Ax1 + By1 + c)  / square root (A² + B²)




Also another problem not related to geometry is this :

When an integer is divided by 15, the remainder is 7. Find the remainders when the same integer is divided by 3 and 5.


Thanks in advance!

Hello.. I'm a new user here.

I'm currently studying Calculus in High School and next semester I'm taking Discreet & Geometry math. I heard it's really tough I'm going to need all the help I can.

I came through this website because I have math problems (I posted the questions in the Help forum).

If I can, I will be glad to help other members.

Anyway it's good to be here... see you guys around!
