How would I solve a problem like this

Ive already done the first two that were similar, but only through trial and error. Ive attempted this next one, but its never right! Create a set of at least five data points such that the standard

2§dy/dx.d^2y/dx^2.dx=? In this problem § denotes integration sign. This problem is assosiatd wid d eqn of SHM

Im assuming that you want to evaluate the following integral: 2 ∫ (dy / dx)(d²y / dx²) dx Note that dy/dx = y (x) and d²y / dx² = y(x) : 2 ∫ y(x) y(x) dx Now make a substitution: u = y(x) du = y

Can anyone help me with this

Solve this i dont really need the steps just the answer. √5-3√5-2√20the √ is a square root--4√ 5-2√20 can be rewritten as 4√5 √5 - 3√5 - 4√5 √5 - 7√5 = -6√5--6√5

Math exam questions. all i need is little help. 10 points for BA.

1. (a^5 + a^4 + a^3 + a^2 + a + 1) / (a^6 - 1) = ? 2. a+b = 1. prove that a^3 + b^3 = 1 - 3*a*b. 3. prove that its wrong: 5*a^2 + 3*b^2 + 20*a - 12*b + 34 = 0.-1. Use (a^6-1)/(a-1)=(a^5 + a^4 + a

Can you please factor this equation. ;D

(1+x)^2(-1)+(1-x)(2)(1+x) thanks-Hello You have only (1+x) as common factor, (1+x)[(1+x)(-1)+(1-x)(2)] = (1+x)[-1-x+2-2x] = (1+x)(1-3x) Hope it helped Bye !-(1+x)^2(-1)+(1-x)(2)(1+x) = (1+x)[(1+x

What is the line of symmetry of y=1/3(x-5)^2-4

thanks :D Do I need to make it into the general form to get -b/2a?-No, you can read it right from the vertex equation if you realize that since x is the squared term, the line of symmetry will be a v
