Algebraic substitution

f(x) = [sin(x)3xcos(4x)/tan(x)arctan(f(x))]/[e^(x^(f(x)^2))ln(3x)cosh(2x)]
g(x) = Sigma, z=1,...,n, n = y/z [ 3sin(z).f(x)/e^i^3]

i)Draw both graphs by subsituting suitable values for each different variable in both the complex and real plane.

ii)Write down the point where the two graphs meet.(You should have two sets of points)

ii)INTEGRATE[f(x)/g(x)].Sin(z(f(x(g(z(x))))

iii)Find the fundemental frequency of g(x) and explain why every wave can be written as a sum of sin functions.

Any chance of doing that in Latex? Or sending a scan/photo of the question

Sorry I don't have latex. I have managed to do the first part of i) but i looked at the qiuestion beforehand and i am struggling with the other parts.

You don't need latex, just type it up in latex in your post.

i.e. Write {tex}type the maths here in a fairly obvious syntax{/tex} except you use square brackets.
You maths typing currently looks like this in tex
Unparseable latex formula:

f(x) = [sin(x)3xcos(4x)/tan(x)arctan(f(x))]/[e^(x^(f(x)^2))ln(3x)cosh(2x)][br]g(x) = Sigma, z=1,...,n, n = y/z [ 3sin(z).f(x)/e^i^3]



Use preview to get something looking sensible and then repost.

Starters in latex for you
Use ^ for power
x_i for x subscript i
\int for integral
\int_1^\pi for integral from 1 to pi \pi will parse into greek
