Math Tutorial?

Today, I'll be teaching a little bit of geometry, so if you have any questions just e-mail.





Perimeter Formulas:





Square: 4s





Triangle: Sum of the Sides





Rectangle: 2(l+w)





Equilateral Triangle: 3s





Circle(Circumference) (2)(pi)(r)





A perimeter of any shape is the length of the lining surrounding the shape.





Area Formulas:





Square: s^2, d^2/2





Triangle: 1/2bh, 1/2(sina)(b)(c)





Equilateral Triangle: (sqrt3/4)(s^2)





Rectangle: (l)(w)





Circle: (pi)(r^2)





Ellipse: (pi)(a)(b)





Trapeziod: [ h(b1+b2) ] / 2





Volume Formulas:





Cylinder: (pi)(r^2)(h)





Cone: (1/3)(pi)(r^2)(h)





Rectangular Prism: (l)(w)(h)





Cube: s^3





Pyramid: (1/3)(l)(w)(h)





Sphere: (4/3)(pi)(r^3)





Surface Area:





Cylinder: (2)(pi)(r^2) + (2)(pi)(r)(h)





Cone: (pi)(r)^2 + (pi)(r)(slant)





Rectangle: (2lh) + (2lw) + (2wh)





Cube: (6)(s^2)





Square Pyramid: (s^2) + (1/2)(s^3) + (2)(h^2)(s)





Sphere: (4)(pi)(r^2)





s = side


l=length


w=width


d=diagonal


h=height


r=radius

Yeah I need help proving Goldbach's conjecture. Thanks.
Reply:No one will answer a question that is so long. You have to break it to one of two question each submitted separately
