f(x) = ln(4x^2 +5x-3) - I think you find the deriv of the outside, put the inside back..then find the deriv of the inside?
So my soln would look like: 1/x(4x^2+5x+3) * (8x+5)? is that right?
6xsecx+xtan(x) - so we use the product rule for 6xsecx..then product rule for xtanx also?
(6x)(secx) = (6)(secx)+(6x)(secxtanx) + (1)(tanx)+(x)(sec^2x)?
And I wrote in my previous post a problem that involved a diver diving off a platfrom 16ft with initial velocity of 32ft/sec...and someone told me it couldn't be done because u need to know the direction of the initial velocity..But I received the same problem on the test and yea..couldn't do it..but why can my teacher do a problem that is said to be undoable?
She mentioned something about usiing 9.8ft/sec or something and b/2a...so can anyone also explain this to me?
