ln(sec(pi/4)+tan(pi/4))

ln (sec (\frac{π}{4}) + tan (\frac{π}{4}))

ln (2 + 1)

Solution steps

ln (sec (\frac{π}{4}) + tan (\frac{π}{4}))

Use the following trivial identity:

sec (\frac{π}{4}) = 2

Use the following trivial identity:

tan (\frac{π}{4}) = 1

= ln (2 + 1)

\frac{5.5}{cos ( 6 1 ^{\circ} )}

arctan (\frac{6}{- 2})

arcsin (- \frac{3}{8})

cos (\frac{5 π}{12}) + cos (\frac{π}{12})

tan (0.3)
