thanks
switch y and x, and solve for y.
\(\large\color{slate}{ y=1/2~\sin x }\) switch \(\large\color{slate}{ y}\) and \(\large\color{slate}{ x }\). What do you get after doing so?
x=1/2 sin y ?
yes.
Now, multiply both sides times 2 for me please.
idk wait like what 2/4
\(\large\color{slate}{ x=1/2~\sin (y)~}\) multiplying both sides times 2 , \(\large\color{slate}{ x\color{blue}{\cdot 2}=1/2~\sin (y)~\color{blue}{\cdot 2} }\) What do you get then?
(what cancels out on the right side ?)
2x=sin(y)?
yes.
now, we know that: If: \(\large\color{slate}{ \rm{sin{\small~}}(\color{blue}{A})=\color{red}{B} }\) Then: \(\large\color{slate}{ \rm{Arc{\tiny~}sin{\small~}}(\color{red}{B})=\color{blue}{A} }\)
And so, If: \(\large\color{slate}{ \rm{sin{\small~}}(\color{blue}{y})=\color{red}{2x} }\) Then: \(\large\color{slate}{ \rm{Arc{\tiny~}sin{\small~}}(\color{red}{~?~})=\color{blue}{y} }\)
2
2 ?
it would be arcsin(2) ??
or did you mean something else?
y=2 arcsin x?
Again the rule is: ~~~~~~~~~~~~~~~~~~~~~~ If: \(\large\color{slate}{ \rm{sin{\small~}}(\color{blue}{A})=\color{red}{B} }\) Then: \(\large\color{slate}{ \rm{Arc{\tiny~}sin{\small~}}(\color{red}{B})=\color{blue}{A} }\)
~~~~~~~~~~~~~~~~~~~~~~ If: \(\large\color{slate}{ \rm{sin{\small~}}(\color{blue}{y})=\color{red}{2x} }\) ~~~~~~~~~~~~~~~~~~~~~~ your \(\large\color{slate}{ \rm{{\small~}}\color{blue}{A} }\) is y . your \(\large\color{slate}{ \rm{{\small~}}\color{red}{B} }\) is 2x .
wait so y=arcsin2x
yes, \(\large\color{slate}{ y={\rm Arcsin}(2x) }\)
\(\large\color{slate}{ \color{blue}{y}={\rm Arcsin}(\color{red}{2x}) }\) see the A and B thingy here?
yes i do thanks so much
