23
Q

integral of sin

24
Q

integral of cos

25
integral of 1/x
lnx + c = lnB where B = e^c
26
integral of 5x^4
x^4+1 / 4+1 = 5 (x^5/5) = x^5
27
For the chain and product rules what is important to know about v and u?
they are UNDIFFERENTIATED when subbed in at the end
28
what is the difference between partial and full differentiation?
partial = whatever isn't in the d/d(?) is left as constant so not written in the answer full = e.g. dy/dx both x and y are differentiated
29
what is the conversion from ln to log?
ln = 0.0592 log
