117.8 because angle at a point add up to 360 so 360 -(90 + 38.2+31.7+82.3) =117.8

Find the slope of the normal line to y=x+cos(xy) at (0,1)

DaniilM [7]

Derivating the equation:

$y=x+\cos(xy)\Longrightarrow y'=1+(-y\sin(xy)-xy'\sin(xy))\iff \\\\y'=1-y\sin(xy)-xy'\sin(xy)\iff y'+xy'\sin(xy)=1-y\sin(xy)\iff \\\\y'=\dfrac{1-y\sin(xy)}{1+x\sin(xy)}$

So the slope of the tangent in the point (0,1) is:

$y'=\dfrac{1-y\sin(xy)}{1+x\sin(xy)}\Longrightarrow y'=\dfrac{1-1\sin(0\cdot1)}{1+0\sin(0\cdot1)}\Longrightarrow y'=1$

Then, the slope of the normal (n) line in the point (0,1) is:

$n\cdot y'=-1\Longrightarrow n\cdot1=-1\iff\boxed{n=-1}$
