Answer:
begin mathsize 16px style straight I equals integral tanx space dx
straight I equals integral sinx over cosx dx
If space straight f left parenthesis straight x right parenthesis equals cosx rightwards double arrow straight f apostrophe left parenthesis straight x right parenthesis equals negative sinx
straight I equals negative integral fraction numerator negative sinx over denominator cosx end fraction dx
straight I equals negative log open vertical bar cosx close vertical bar plus straight c
straight I equals log open parentheses cosx close parentheses to the power of negative 1 end exponent plus straight c
straight I equals log open vertical bar secx close vertical bar plus straight c end style
