(cos^2(pi/4))/(sqrt(2))

\frac{cos ^{2} ( \frac{π}{4} )}{2}

\frac{2}{4}

Solution steps

\frac{cos ^{2} ( \frac{π}{4} )}{2}

Use the following trivial identity:

cos (\frac{π}{4}) = \frac{2}{2}

= \frac{( \frac{2}{2} ) ^{2}}{2}

Simplify

\frac{( \frac{2}{2} ) ^{2}}{2} : \frac{2}{4}

= \frac{2}{4}

arctan (\frac{6}{17})

29 \cdot cos (- 5.9 1^{\circ})

2 (1)^{2} + 2 arcsin (1)

sin (7 \cdot \frac{π}{2})

csc (\frac{2}{2})
