What is amplitude and period of f(t)= -tan 0.4 t

No Amplitude

Period =  

Step-by-step explanation:

We can say a general function for Tan function as:

This function given is:

f(t) = - Tan (0.4t)

First of all, there is no amplitude for a tan function because it goes on and on in both y-directions. THere is no max or min value, so there is no Amplitude.

As for period, the normal period (distance between 2 vertical asymptotes of a tan function) is  (180 degrees).

Since this function has a b value, the period would be:

So,

b = 0.4, so we have:

THis is the period , in terms of pi.

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
