How do you integrate log(y)/y? can it be seperated into integral of log y +integral of 1/y??
∫log(y) dy/y
integrate by parts
let u = log(y): dv = dy/y
du = dy/y : v = log(y)
∫u dv = uv - ∫v du
∫log(y) dy/y = [log(y)]^2 - ∫log(y) dy/y
add ∫log(y) dy/y both sides
2 ∫log(y) dy/y = [log(y)]^2
divide by 2
∫log(y) dy/y = (1/2) [log(y)]^2 + c
½ln²(y) + C
Basic problem utilizing the Integration by Parts technique
