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

Solution

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

Solution

ln (1 + 2)

+1

Solution steps

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

Use the following trivial identity:

tan (\frac{π}{4}) = 1

Use the following trivial identity:

sec (\frac{π}{4}) = 2

= ln 1 + 2

Simplify

ln 1 + 2 : ln (1 + 2)

= ln (1 + 2)
