1. Encuentra el módulo de

z

:

|z| = \sqrt{(-4)^2 + (-3)^2} = 5

2. Encuentra el argumento de

z

:

\theta = \tan^{-1}\left(\frac{3}{4}\right) + \pi \approx 3.7851

3. Expresa en forma polar:

z = 5 \left(\cos(3.7851) + i \sin(3.7851)\right)

Exercise The temperature T in degrees Celsius of a chemical reaction is given as a function of time t, expressed in minutes, by the function defined on ¿ by: T (t )=(20 t +10)e−0.5t. 1) What is the initial temperature? 2) Show that T' (t )=(−10 t +15)e−0 .5t. 3) Study the sign of T' (t ), then draw up the table of variations of T . We do not ask for the limit of T in +∞. 4) What is the maximum temperature reached by the reaction chemical. We will give an approximate value to within 10−2. 5) After how long does the temperature T go back down to its initial value? We will give an approximate value of this time in minutes and seconds.
