Explicação passo a passo:

a)

$f\left(\sin \left(\alpha \right)\right)=\sin \left(180-\alpha \right)$

$f=\sin \left(180-\alpha \right)$

$\sin \left(180-\alpha\right)=f$

$180-\alpha=\arcsin \left(f\right)+2\pi n,\:180-\alpha=\pi +\arcsin \left(-f\right)+2\pi n$

$\alpha=-\arcsin \left(f\right)-2\pi n+180,\:\alpha=-\pi +180-2\pi n-\arcsin \left(-f\right)$

$f\left(\sin \left(\alpha \right)\right)=\sin \left(180+\alpha \right)$

$f=\sin \left(180+\alpha\right)$

$\sin \left(180+\alpha\right)=f$

$180+\alpha=\arcsin \left(f\right)+2\pi n,\:180+\alpha=\pi +\arcsin \left(-f\right)+2\pi n$

$\alpha=\arcsin \left(f\right)+2\pi n-180,\:\alpha=\pi +\arcsin \left(-f\right)+2\pi n-180$

$f\left(\sin \left(\alpha \right)\right)=\sin \left(360-\alpha \right)$

$f=\sin \left(360-\alpha\right)$

$\sin \left(360-\alpha\right)=f$

$360-\alpha=\arcsin \left(f\right)+2\pi n,\:360-\alpha=\pi +\arcsin \left(-f\right)+2\pi n$

$\alpha=-\arcsin \left(f\right)-2\pi n+360,\:\alpha=-\pi +360-2\pi n-\arcsin \left(-f\right)$

b)

$f\left(\cos \left(\alpha \right)\right)=\cos \left(180-\alpha \right)$

$f=\cos \left(180-\alpha \right)$

$\cos \left(180-\alpha\right)=f$

$180-\alpha=\arccos \left(f\right)+2\pi n,\:180-\alpha=-\arccos \left(f\right)+2\pi n$

$\alpha=-\arccos \left(f\right)-2\pi n+180,\:\alpha=\arccos \left(f\right)-2\pi n+180$

$f\left(\cos \left(\alpha \right)\right)=\cos \left(180+\alpha \right)$

$f=\cos \left(180+\alpha \right)$

$\cos \left(180+\alpha\right)=f$

$180+\alpha=\arccos \left(f\right)+2\pi n,\:180+\alpha=-\arccos \left(f\right)+2\pi n$

$\alpha=\arccos \left(f\right)+2\pi n-180,\:\alpha=-\arccos \left(f\right)+2\pi n-180$

$f\left(\cos \left(\alpha \right)\right)=\cos \left(360-\alpha \right)$

$f=\cos \left(360-\alpha \right)$

$\cos \left(360-\alpha\right)=f$

$360-\alpha=\arccos \left(f\right)+2\pi n,\:360-\alpha=-\arccos \left(f\right)+2\pi n$

$\alpha=-\arccos \left(f\right)-2\pi n+360,\:\alpha=\arccos \left(f\right)-2\pi n+360$
