1. find the equation of the tangent to the curve y=loge(5x+4) at the point where x=3.
How do i do this? Show working out too please
First i y' it so i got...>> 5
----------
5x+4
Do i sub x=3 in now? So i will get.. 5/19.
Whats next? i think i did it wrong after this step.
I found y but its a decimal. i tried subbing in the y-y1=m(x-x1) but it came out wrong!
So i need ya help
