Exercise 5:1

Write the formulas in TeX , you can test your text in the editor to your individual assignment.

a) \displaystyle \displaystyle\frac{a+b}{d-c} b) \displaystyle \sqrt{3}
c) \displaystyle 4x^2 - x d) \displaystyle \sin^2 x + \cos x

Exercise 5:2

Write the formulas in TeX

a) \displaystyle x^3y^2\left(\displaystyle \frac{1}{y} - \frac{1}{xy}+1\right) b) \displaystyle \left(x-y+\displaystyle\frac{x^2}{y-x}\right) \left(\displaystyle\frac{y}{2x-y}-1\right)
c) \displaystyle \displaystyle\frac{a-b+\displaystyle\frac{b^2}{a+b}}{1-\left(\displaystyle\frac{a-b}{a+b}\right)^2} d) \displaystyle \displaystyle \frac{1}{1+\displaystyle \frac{1}{1+\displaystyle \frac{1}{1+x}}}


Exercise 5:3

Write the formulas in TeX

a) \displaystyle \cos{v} = \cos{\displaystyle \frac{3\pi}{2}} b) \displaystyle \tan\displaystyle\frac{u}{2}=\frac{\sin u}{1+\cos u}
c) \displaystyle \left\{\eqalign{

x&=n\pi\cr x&=\displaystyle \frac{\pi}{4}+\displaystyle \frac{n\pi}{2} }\right.

d) \displaystyle \bigl(\sqrt[\scriptstyle4]3\,\bigr)^3\ \sqrt{2 + \sqrt{4}}
