If in some integration, I see the derivative of the base sitting there either directly or as a multiple, the integration becomes routine. so intgr x^2(x^3 - 6)^3 = x^2/(4(3x^2))(x^3 - 6)^4 + c = (1/12)(x^3 - 6)^4 + c check it by differentiating, it works.

This is an IVP (initial value problem). x"(t)=(6t-4) ms-2 ....(1) "...if the particle is at origin and has a velocity of ? when t=0." Integrate (1) with respect to t to find x'(t) and x(t). Do not forget the integration constants at each integration. Use the initial conditions...

**Calculus**

The S thingy is called the integral sign. The number at the bottom (1) is the lower limit of a definite integral, and the top number (9) is the upper limit of integration. The expression to be evaluated probably looks similar to this: I = ∫19 (4*x^2+5)/sqrt(x) dx If you use ...

**Math**

The best method here is integration by parts. Most of the times when you see products of functions AND the product of one with the others derivative gives a simple to integrate function. Do you see that [ln(x)]' = 1/x. And when you multiply it with a power of x you get a power...

**Calculus**

We do not see the figure, but could probably help anyway. Along whichever axis you do the integration, the method is to cut up the volume into slices perpendicular to the x-axis, say. Each slice is of thickness dx and the width and height will be a function of y and z, which ...

**Calculus please help!!! double integral**

Combine the following two integrals into one by sketching the region, then switching the order of integration. (sketch the region) im gonna use the S for integral sign..because idk what else to use. SS6ycos(x^3-3x)dxdy+SS6ycos(x^3-3x) And the first integration limits for x are...

First of all, you have to visualize what the surface of revolution is. You get it by rotating a line (straight or curved) 360 degrees about an axis, like the outside of a vase or pot being made on a lathe or potter's wheel. Draw yourself a figure with the three lines plotted. ...

integrate -2/xln^4(x)...plz help me..give me an idea on how to start..plz The derivative of the ln(x) function is 1/x and this is multiplying the ln^4(x). You can thus write the integral as: -2 * 1/5 ln^5(x) + constant. is that the answer? wut about the x infront of ln^(x)......

**drwls & Damon - maths**

My first suggestion was to try the method of "integration by parts", but that may not work. I found a recursion formula for the integral in my Table of Integrals, but it ends up requiring the integral of e^-x/x , which is a new fucntion called the exponential integral, Ei(x). ...
