Solution steps

cot (arcsec (17))

Rewrite using trig identities:

cot (arcsec (17)) = \frac{1}{17 1 - \frac{1}{( 17 ) ^{2}}}

Use the following identity:

cot (arcsec (x)) = \frac{1}{x 1 - \frac{1}{x ^{2}}}

= \frac{1}{17 1 - \frac{1}{( 17 ) ^{2}}}

= \frac{1}{17 1 - \frac{1}{( 17 ) ^{2}}}

Simplify

= \frac{1}{4}

31 cos (4 5^{\circ})

sec (49.9 6^{\circ})

tan (arccos (\frac{7}{11}))

sec (arctan (\frac{3 2}{2}))

\frac{10 0 ^{2} ( 2 sin ( 3 0 ^{\circ} ) )}{9.8} - 999.984741
