sin(x)^2+cos(x)^2=C
How do i solve for x?
>>8817137
x can literally be anything because C is always 1.
>how do i solve the idiot formula
Define a function $f(x)=\sin^2(x)+\cos^2(x)$ and take the derivative. Turns out that the derivative is zero, which means that the function is constant. Taking an arbitary $x$ solves the "equation" for $C$. Another approach would be to not be a brainlet and apply the popular formula...

I dont relly care what B equals, i just want it to stand alone on one side of the =
>>8817137
You don't without introducing extra variables.

What the fuck are you on about? It is always one by definition of sin and cos. Fucking leave this board, brainlet.

sin(x)^2+cos(x)^2=C
sin(x)^2 = 1/2 * (1-cos(2x))
cos(x)^2 = 1/2 * (1+cos(2x))
.'. sin(x)^2+cos(x)^2=C == 1/2 + 1/2 == 1
>>8817137
arccos((1-cos(2x))/2 + cos(x)^2) = arccos(C)
arccos(1/2) - x + x^2 = arccos(C)
x^2 - x + (Arccos(C+1/2)) = 0
solve quadratic and you get 2 values for x.
sin(x)^2+cos(x)^2=1 so C=1
from there you have sin(x)^2+cos(x)^2=1
or 1=1 from before
therefore x∈R

Let [math]\mu[/math] be the Lebesgue measure. Then [math]\mu({1})=0[/math], so [math]C \neq 1[/math] almost everywhere.
>>8817664
Oops, [math]\mu(\{ 1\})=0[/math].

Actually fucking always brainletto
