When solving cubic equations using Cardano's Method, interesting ways to write simple numbers arise.  In the case with this cubic, the golden ratio φ and its reciprocal 1/φ were used to give the answer of 1.

WHY DO I HAVE TO STUDY LOGARITHMS
1] Sin( ) is a measure of how much perpendicular two objects/forces are. 
2] i = rotation by 90 degree. i^2 = rotation by 180 degree
3] Transpose of a matrix = matrix rotating by 180 degree.
4] Log (any effect ) = the cause that caused it.
5] dx---> keep adding in the direction of x

0] Sin() = measure of how perpendicular two forces are
1] i = rotation by 90 degrees. i^2= rotation by 180 degrees
2] log(effect) = cause
3] Transpose of a matrix = rotation by 180 degrees
4] Diagonal of a matrix = axle of rotation.
5] Curl = ability of a field to make you spin or revolve.

INTEGRATION INTUITIVELY EXPLAINED
https://gumroad.com/l/JXwPU
visualizingmathsandphysics.blogspot.in
(1) Why sin(30) = 1/2 ?
(2) i ^ 2 = -1 = rotation by 180°
(3) Transpose [A] = Rotation by 180.
(4) Diagonal of a matrix = Its axis of rotation.
(5) Why A x B = ABsin( )??
(6) Why Log(A x B) = Log(A) + Log(B) ???
(7) What is the purpose of curl and divergence??
(8) Purpose of differential equations.
For (5$)

About this community

This community is specifically about the kind of mathematics needed to succeed in the various mathematics competitions around the world. The types of questions are often very different from standard school maths. This Mathematics Competitions community includes practice questions and learning materials. The overall aim is to improve your mathematical thinking skills. there is now a <spam trap>. As spammers are too lazy to read, it is normal to have it as the default top category. So please take some care when selecting an appropriate category - it must take all of 3 seconds to do so! Managed by GiftedMathematics.com

I've started a channel of maths tutorials. I have two videos so far, one is on differentiation and one is on root-two. Please subscribe, feedback is welcome.

I would suggest writing in a darker, thicker pen. It is difficult to see. Otherwise it was nice.
