simplify ln(e^xcos(x))

Solution

simplify

ln (e^{x} cos (x))

Solution

x + ln (cos (x))

Solution steps

ln (e^{x} cos (x))

Apply log rule:

lo g_{c} (ab) = lo g_{c} (a) + lo g_{c} (b)

ln (e^{x} cos (x)) = ln (e^{x}) + ln (cos (x))

= ln (e^{x}) + ln (cos (x))

Apply log rule:

lo g_{a} (x^{b}) = b \cdot lo g_{a} (x)

ln (e^{x}) = x ln (e)

= x ln (e) + ln (cos (x))

x ln (e) = x

= x + ln (cos (x))
