Find the six trig function values of $(\frac{- 7 π}{4})$ $((-7pi)/4)$

Explanation:

$sin (\frac{- 7 π}{4}) = sin (\frac{π}{4} - 2 π) = sin (\frac{π}{4}) = \frac{\sqrt{2}}{2}$ $sin ((-7pi)/4) = sin (pi/4 - 2pi) = sin (pi/4) = sqrt2/2$
$cos (\frac{- 7 π}{4}) = cos (\frac{π}{4} - 2 π) = cos (\frac{π}{4}) = \frac{\sqrt{2}}{2}$ $cos ((-7pi)/4) = cos (pi/4 - 2pi) = cos (pi/4) = sqrt2/2$
$tan (\frac{- 7 π}{4}) = \frac{sin}{cos} = 1$ $tan ((-7pi)/4) = sin/(cos) = 1$
$cot (\frac{- 7 π}{4}) = \frac{1}{tan} = 1$ $cot ((-7pi)/4) = 1/(tan) = 1$
$sec (\frac{- 7 π}{4}) = \frac{1}{cos} = \frac{2}{\sqrt{2}} = \sqrt{2}$ $sec ((-7pi)/4) = 1/(cos) = 2/sqrt2 = sqrt2$
$csc (\frac{- 7 π}{4}) = \frac{1}{sin} = \frac{2}{\sqrt{2}} = \sqrt{2}$ $csc ((-7pi)/4) = 1/(sin) = 2/sqrt2 = sqrt2$
