Find values of trig expression

Ans: $\frac{7 \sqrt{2}}{2}$ $(7sqrt2)/2$

Explanation:

$arctan (1) = \frac{π}{4}$ $arctan (1) = pi/4$ --> $cos (\frac{π}{4}) = \frac{\sqrt{2}}{2}$ $cos (pi/4) = sqrt2/2$
$3 csc (\frac{π}{4}) = \frac{3}{sin (\frac{π}{4})} = (3) (\frac{2}{\sqrt{2}}) = \frac{6}{\sqrt{2}} = \frac{6 \sqrt{2}}{2}$ $3csc (pi/4) = 3/(sin ((pi)/4)) = (3)(2/sqrt2) = 6/sqrt2 = (6sqrt2)/2$
$cos (\frac{π}{4}) + 3 csc (\frac{π}{4}) = \frac{7 \sqrt{2}}{2}$ $cos (pi/4) + 3csc (pi/4) = (7sqrt2)/2$
