change of base the final topic that we have to look at in this section is the change of base formula for logarithms the change of base formula
write following in terms of simpler logarithms a log3 9 x4 radicysolutionlog3 9 x4 radicy log shy3 9x4 - log y 12log shy3 9 log
properties1 the domain of the logarithm function is 0 infin in other terms we can just plug positive numbers into a logarithm we cant
logarithm functions in this section well discuss look at a function which is related to the exponential functions we will learn logarithms in this
definition of natural exponential function the natural exponential function is f x ex where e 271828182845905 hence since e gt 1 we also
natural exponential function there is a extremely important exponential function which arises naturally in several places this function is called as
general approach of exponential functions before getting to this function lets take a much more general approach to things lets begin with b 0 b ne
solve 5x tan 8x 3x solution firstly before we even begin solving we have to make one thing clear do not cancel an x from both sides whereas
solve 8 cos2 1 - x 13 cos1 - x - 5 0 solutionnow as specified prior to starting the instance this quadratic does not factor though that doesnt
