First off, note that ln(1) is an actual constant and simplifies to 0. The problem is now reduced to (VKC)/F=(1+E)*0-EX So now, you have a variable multiplied by X. To get rid of it, you want to divide both...

Firstly, solving the original equation. x/3 = y + 2/3. Multiplying everything by 3 leaves x = 3y + 2. Now that we have an equation for x, we can solve the expression (x + 7)/3. Using the formula for x above, x + 7 = (3y + 2) + 7 = 3y + 9. Then, (x + 7)/3 = (3y + 9)/3 = y + 3...

Note that the characteristic of this equation is: y^2 + 1 = 0. This solves to yield y = ±i and the solutions would be: y = K*sin(t) + C*cos(t), for some constants K and C. I hope this helps!

Suppose that you know that m = 2 and

**c**= 3. You need to examine the x- and y- asymptotes. There is no way that x could equal 0 in this equation because any number divided by 0 is undefined, so if you were to substitute 0 for x in the equation you would get y...3 Answers · Science & Mathematics · 24/08/2008
