1 day ago · In mathematics, sine and cosine are trigonometric functions of an angle. The sine and cosine of an acute angle are defined in the context of a right triangle: for the specified angle, its sine is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse ), and the cosine is ...
1 day ago · Bessel himself originally proved that for nonnegative integers n, the equation J n (x) = 0 has an infinite number of solutions in x. When the functions J n (x) are plotted on the same graph, though, none of the zeros seem to coincide for different values of n except for the zero at x = 0.

In mathematics, the Riemann hypothesis is the conjecture that the Riemann zeta function has its zeros only at the negative even integers and complex numbers with real part 1 2. Many consider it to be the most important unsolved problem in pure mathematics. [1]
