6.2 Trigonometric Functions: Unit Circle Approach/33

$\sin {90^{\circ }}+\tan {45^{\circ }}=1+{\frac {\frac {\sqrt {2}}{2}}{\frac {\sqrt {2}}{2}}}$
$1+{\frac {\frac {\sqrt {2}}{\cancel {2}}}{\frac {\sqrt {2}}{\cancel {2}}}}\cdot {\cancel {2}}=1+{\frac {\sqrt {2}}{\sqrt {2}}}$
$1+{\frac {\sqrt {2}}{\sqrt {2}}}=1+1=2$
