asinus

f(x)= 3cos(3x) Durch eine Verschiebung des Kosinus-Graphen erhält man den Sinus-Graphen. Man kann also f auch als Sinus-Funktion darstellen. Wie sieht die Funktion f in der Darstellung mit Sinus aus?

f(x)=?

$f(x)=3cos(3x)$

$g(x)=3sin(3x)$     

g(x) ist um ${\color{blue}\frac{5\pi}{6}}$ nach plus x verschoben.

${\color{blue}f(x)=3cos(3x)=3sin(3\times(x+\frac{5\pi}{6}))}$

8' 7 1/4" divided by 16

$8'\ 7\frac{1}{4}'':16$

$\large{\frac{8'\times\frac{12''}{1'}+\frac{29''}{4}}{16}=\frac{\frac{96''\times4+29''}{4}}{16}=\frac{103\frac{1}{4}''}{16}}$

$=\frac{103}{16}''+\frac{1}{64}''=6\frac{28}{64}''+\frac{1}{64}''$

${\color{blue}=6\frac{29}{64}''}$    !

whats -8 divided by -4x

${\color{red}\frac{-8}{-4y}}{\color{blue}\ =\ \frac{2}{y}}$    !

2x+3y=10

$y=-\frac{2}{3}x+\frac{10}{3}$

            p           q

$if \ \ y\ =\ 0 \ then$

$-\frac{2}{3}x+\frac{10}{3}=0$

${\color{blue}x = 5}$    !

Greeting asinus :- =    !

what is 17.5% of £3.20

${\color{red}£3.20 \times17.5\%}= \frac{£3.20\times 17.5}{100}={\color{blue}£0.56}$

  !

what is 4- 4/3* 5/4+ 11/6

$4-\frac{4\times5}{3\times4}+\frac{11}{6}$

$=\frac{48-20+22}{12}$

$=\frac{50}{12}{\color{blue}\ = 4\frac{1}{6}}$    !

How to calculate the sin of 73°18'42''...?

$73°18'42''= 73° + 18'\times \frac{1°}{60'}+42'' \times\frac{1°}{3600''}$

$=73.3116\overline{6}°$

$sin 73°18'42'' = sin 73.3116\overline{6}°$

${\color{blue}=0.957880987839}$

Find angle X, in the second quadrant whose tangent is -5

$x = arctan (-5)$

${\color{blue}x=101.3099°}$    !

Enter (-5)

Enter " sec atan = " ⇒ -78.6901° (fourth quadrant)

Enter " +180 = " ⇒ 101.3099°    (second quadrant)
