I was reading the text and it said that you must subtract the larger x-value to the smaller x-value. I dont know how you would determine which x value is larger and which is smaller. Please help.

Sorry They way I see the question is: Since Cos pi= -1 and n having six terms from 1 to 6. 1(-1(1)) + 2((-1(2)) + 3(-1(3).... That would give me a totally different answer from the second post...

I am currently stuck on this question. Please help. . . . . . . .6 . . .(Sigma Notation) n cos(n pi) . . . . . .i=1 Thanks!

Thank you so much for the clarification...

Hello. I really need help graphing this equation. I dont know where to start or how to takle this type of equation using calculas. Thanks. g(x)= (|x|+x)/2 * (3x+2) Thank you for your help.

I think I just figured it out! I feel so dumb... Thanks for your help.

Please help... Im trying to figure this out. Find the equation of the tangent line to y=x^2-2x+2 at the point (1,1). THanks for your helps... :P

(x-2)/x/(x-2)(x+2) = 1/x(x+2) Please someone help me by clarifying how the second step is produced. I worked through many options but I cant get to that second step. The way I see it is if a fraction is divided by a fraction then you would multiply the first fraction by the reciprocal of the...

Use the IVT to show that the equation x - cosx = 0 has a solution between x = 0 and x = pi/2. I really do not understand this theorem please some explain this to me.

I am having problems with proving alot of the questions asked in the text book. I don't know what to do or how to start it. For example: a > b <=> a^2 > b^2 (Let a > 0 and b > 0) How would I prove that question? Gr.12 calculas did not really delve into the concept of proving mathematical...

The question asked to solve for x.

Thank you for the clarification. I was thinking the exact same. Thanks again.

Yes I recieved that exact answer... and solving that answer yields: x=1 and x= -1 but the answer on the multiple choice list is x=1.

This question was on a multiple choice test and the answer I recieved was not the same as was on the list. I don't know any other way or direction to takle this question. x^2= d/dx (x^2 - x) I first differentiated the values in the brackets which yields 2x - 1. I then equated the equation to...
