It doesn't hurt to write down the equation again, so let's do so. Equation: 2(Sinhx)² - 5Coshx = 5 . Hmm, we don't really like to do maths w...

There are 4 things we need for a group: associativity, the existence of an identity, inverses in the group and closure. The integers are definitely associative under this operation as addition is associat...

In the case c²>4mk, the characteristic equation has two distinct real roots; this represents overdamping. The system does not oscillate, and x approaches zero as time approaches infinity.In ...

First, form the system into a 3x3 matrix using the coefficients. Find the determinant of this matrix.If the determinant =/= 0, then the matrix is singular and has a unique solution. The system is consiste...

First we establish our base case: f(0) = 2² + 3¹ = 4 + 3 = 7, so clearly f(0) is divisible by 7.Now. by the inductive hypothesis. we assume that f(k) is divisible by 7, and attempt t...
