tan(arccos(1/9))

Solution

tan (arccos (\frac{1}{9}))

Solution

45

+1

Solution steps

tan (arccos (\frac{1}{9}))

Rewrite using trig identities:

tan (arccos (\frac{1}{9})) = \frac{1 - ( \frac{1}{9} ) ^{2}}{( \frac{1}{9} )}

= \frac{1 - ( \frac{1}{9} ) ^{2}}{\frac{1}{9}}

Simplify

= 45

(sin(30))/(sin(22.5))

\frac{sin ( 3 0 ^{\circ} )}{sin ( 22. 5 ^{\circ} )}

(cos(pi/6))/(-sin(pi/6))

\frac{cos ( \frac{π}{6} )}{- sin ( \frac{π}{6} )}

cos^2((3pi)/8)+cos^2(pi/8)

cos^{2} (\frac{3 π}{8}) + cos^{2} (\frac{π}{8})

cos((3pi)/4)+sin((3pi)/4)

cos (\frac{3 π}{4}) + sin (\frac{3 π}{4})
