One of the biggest unsolved mysteries in math is also very easy to write. Goldbach's Conjecture is, Every even number (greater than two) is the sum of two primes. You check this in your head for.. On April 27, 2020 By Prakhar Sharma In My Quora. The Navier-Stokes equation, for me is the hardest of all. This is the full Navier-Stokes equation in conservative form. It looks pretty simple, but as one will dig in, they will notice why it is the hardest one. Meanwhile, W is the vector of conservation variables, F is the Euler flux vector, G.

ANSWER EXPLANATION: To figure out the answer to this question, you'll first need to know the formula for finding the circumference of a circle. The circumference, C, of a circle is C = 2 π r, where r is the radius of the circle. For the given circle with a radius of 1, the circumference is C = 2 ( π) ( 1), or C = 2 π This equation was formed in 1948 by two men named Paul Erdős and Ernst Strauss which is why it is referred to as the Erdős-Strauss Conjecture. 4. Equation Four. Equation: Use 2(2∧127)-1 - 1 to prove or disprove if it's a prime number or not? Looks pretty straight forward, does it? Here is a little context on the problem There are many hard formulae in math. More importantly, there are many equations that are yet to be solved. My favorite being the Riemann Hypothesis. The result implies the distribution of prime numbers. If you are familiar with prime numbers, t.. A very famous equation, Euler's identity relates the seemingly random values of pi, e, and the square root of -1. It is considered by many to be the most beautiful equation in mathematics. A more general formula is When, the value of is -1, while is 0, resulting in Euler's identity, as -1 + 1 = 0 The first way to find the solution is to add the equation, then combine the sum with that of the previous equation. The second solution involves multiplying the second number of the equation by the..

Us engineers didn't see the point in learning proofs. I was very surprised it was supposedly an engineering math class, but had less real problem solving than my other math courses.</p> Physics contains equations that describe everything from the stretching of space-time to the flitter of photons. Yet only one set of equations is considered so mathematically challenging that it's been chosen as one of seven Millennium Prize Problems endowed by the Clay Mathematics Institute with a $1 million reward: the Navier-Stokes equations, which describe how fluids flow

This equation is cleverly disguised as a word problem. The word is means equals, and 5 more than 10 means 15. A simpler way to write this is 10 + x = 15. Subtract 10 from each side of the equation and you get x = 5. Don't forget the last step! The question isn't asking for the value of x, it's asking for 2x. 2 x 5 = 10. The answer is C, 10 (Image credit: Wikipedia user Salix alba) In 2002, a reclusive Russian genius named Grigori Perelman put an end to more than 100 years of suffering in the mathematical community.
